St. Michael’s Hospice family 5k run

May 20th, 2013 No comments

We agreed to enter this fun run as a family and, as soon as we did, the question was how did I run this?  Do I run with the slowest in the family, the fastest, do my own race? If I run with Jack, do I want to beat him? If so, I can’t be anywhere near him within 100m of the finish or he will easily out sprint me.

The run was at Down Grange, on wet grass with mud in places.  As I was tapering for Saturday’s ironman, I did not want to go all out.  I left my watch and HRM at home.  In the end it was agreed that we would run our own race.  I started near the front and went moderately hard to start with.  After the first corner I was about 7th. A ten year old-ish kid was sprinting his heart out for about 100m and then I over took him and a few others and was third.  I stayed likely that, running hard but nowhere near all out.

The guys running the 10k fun run started two minutes ahead of us and I soon started catching them, weaving in and out of people and skipping and jumping over mud.  At 3k someone over took me.  I don’t think he was trying too hard, but who knows.  So I came in in 4th, in just over 20 minutes.  Who knows how long the course actually was though!

I then ran back along the course and found Jack and when he got near the finish, I ran with him.  He started sprinting too soon (gaining 5m almost instantaneously) but I caught him and beat him to the finish.  He sprinted too far out, but still finished in under 24 minutes so a great result.

Ironman Lanzarote 2013 – race report

May 20th, 2013 1 comment

IMAG0542

In the months building up to the race

I started highly motivated, training well, consistently and losing weight.  Then in about October 2012 the training started to get less consistent and the weight loss got put into reverse. 

My bike hours decreased a lot – my bike broke while I was on holiday in Lanza over Christmas, the winter was cold, snowy and icy.  I was also uncomfortable with my saddle (chaffing) and so tried three different ones in each of my last three long rides.  In the end I stuck with the third one (which I used to use before I bought my new ones) but it still chaffed.  I don’t think I did any interval training since October (well maybe a couple of gentle ones, but none worth talking about). I did get myself some rollers and they allowed me to get the odd hour in but again, just an easy ride, not many intervals.  In March, my time on the bike reached a whole eight hours.

Swim wise, I started going two times a week but didn’t seem to improve.  The swim sessions I was given were complex, and so hard to remember, and had target times that I rarely could meet.  In the end I gave up on that and just tended to swim slowly, without any direction or purpose.  Also, they tended to be relatively short swims, just a couple of k. 

Run wise, I was saved by my regular long run with Ashley.  If I hadn’t of done that then my run volume would have been low, rather than just questionable.  The runs with Ashley started off at ironman pace but gradually got faster and faster so that I struggled with the pace on the last few.  He’s improved so much more than me! But while we regularly ran 21k, I didn’t do any runs that we’re substantially longer than that.  Also, the weekday running turned into a gentle run.  Very few intervals or tempo runs.  But I was running at my best.  I got a PB for 10k and the half-marathon so something was going very well. 

So going into Lanza, I was nervous about by swim as I was a lot slower than before.  I was confident I’d get around the bike but again slower than before.  I was nervous about the chaffing issue though – that would be mentally distracting as well as painful.  Run wise, I was confident – but only if my pins and needles/numbness issue was solved.

Before the race

We got to Lanza late on Thursday.  The flight was delayed a bit and we got to the hotel around 10pm.  The reception was closed but we knew that there would be a note in the window explaining how to find the room (we’d told them a week ago that we would be late and they had sent an email back explaining the procedure).  So I dropped Catherine off with the bike box and bags and then spent about 10 minutes finding a parking space and running back.  I got there but there was no note.  No room.  Sleep in the car?  Er, no/  So I then ran back to the car and drove back, picked up Catherine and the bags and then set off to find a hotel.  Fortunately we did but only for one night. They didn’t have a room for the weekend.  Friday morning was spent worrying about finding a bed, registering for the race, building my bike and testing it.  In the end, we called the original hotel, they were very sorry and now we had a bed.  Everything else went well.

Race day

I woke up at 4:45, had a couple of boiled eggs and then set off for transition at 6am.  As I started to walk down, it started to drizzle.  As I queued for the toilets, it started raining harder. As I put my wetsuit on it rained harder.  I then gave my bag in and walked down to the swim start

The swim

I started about 8m back from the front.  So there were probably 25 people or more people directly ahead of me, and more ahead to the sides.  This was much further back than before, but I was expecting to be slower than before.  As soon as the helicopter turned up we started and it was a walk in to the water because of the number of people, and not the run I was used to.  It started to get pretty surreal.  If you imagine people standing on a crowded tube train, they get quite close to each other.  That’s what waiting to start was like.  if you then get those people to waive their arms around, people will get hit.  And that is what the start was like. I think when people are uncomfortable in the water they start to swim breast stroke.  I don’t because I can’t, but others seem to.  So I was not able to swim front crawl because of the people breast stroking in front and beside of me.  It turned into a bit of a doggy paddle because if I did swim front crawl I swam over the person in front of me.  The people behind had the same problem in that they kept swimming over me because I was going so slow.  It was very frustrating.

I had started on the far left (shortest route) and after a bit of this I followed some others and dipped under the rope and swam parallel.  I then swam back over the rope and carried  on around the buoy.  Did I feel panicked? Yes, a bit.  I couldn’t go forward as I was being blocked.  I kept on getting kicked from all sides and people seemed to be pushing my legs down as they swam over me. Going under the rope for a bit was the safe route for me.  I still went around the buoy and didn’t cut any corners but it felt safer.  The rest of the swim was done at an “easy” intensity.  I actively drafted a bit, but not that much.  When I got squished between people, I just increased the intensity a bit to get ahead.

After the first buoy, I remember the smell of petrol fumes and a lady on a motor boat whistling at people to get the other side of the buoys.  I am not sure how I know that the whistler was a lady, perhaps I heard her shout at people too?  Perhaps it was my imagination.

The rest of the lap was pretty uneventful, just easy swimming, occasionally looking up to see how far the turn around buoy was.  I saw the clock say 30:44 as I got near the edge of the water but I knew I would be slower so that was fine. 

The second lap was pretty uneventful too. No whistling, no petrol, no fighting, no jellyfish and less bubbles. I did get to see a few schools of little fish in the depths.  I overtook someone in a yellow cap (male pro) and at the end of the second lap someone in a green hat (female pro) but I think she made it to the timing mat before me. Again, the pace was easy.

Time was something like 62:40 so I had slowed (47 seconds) but that was expected.

T1

On the run up the beach, I took my goggles, hat and top half of my wetsuit off.  I took time to change in to cycling bib shorts as they are more comfortable that my tri shorts and I was nervous about chaffing.  Then a good dollop of white sun tan cream and I was off to my bike, carrying my shoes, helmet, glasses and bike computer. Its quite a run.  Then I get my bike and run carrying my shoes until just before the exit where I put them on and then got away. Another long run, transition is definitely getting longer each year.

Time 7:35 – this reflects the huge amount of running involved, and a bit of a delay putting on the cycle kit.

Bike

Immediately outside transition there were people weaving all over the place trying to get into their bike shoes but after dodging them I settled in to the ride.  I worked by power to start with as my HR is normally quite high after T1 but it was only a little higher as I had taken it a bit easier in the swim.  After I got settled on the bike, I notice the constant stream of people going by me.  I am used to that but it is demoralising all the same.

After three km or so I heard a crashing sound to my right and I looked around to see a man on the floor.  He had been riding a mountain bike on the pavement and hit a bench.  Weird.

At the second roundabout there was a policeman telling us to slow down around the roundabout.  As I did, there was someone sitting on the curb with a bit of road rash.  The ground was still wet from the rain.  After doing the El Golfo loop I also saw a man being attended by an ambulance, he had a lot of road rash.

People kept overtaking me until I got to Teguise.  I guess the flood of people turned to a trickle once we crossed Fire Mountain but after Teguise it reduced noticeably.  I was eating and drinking regularly.  By this stage, I noticed that almost everyone beat me up a hill but I then gained on them again on the crest / downhill part.  The view at the top of the island was superb again.  On the climb to the view point, I noticed that I lost about 50m to a few people on the steeper bit but gained 100m on when the gradient eased off.

The downhill started cautiously.  The road was rough.  The wind was strong and gusty.  I had three people ahead of me.  And an ambulance was tending someone who had fallen.  None of these is conducive to going fast on my aerobars.  So I didn’t race down to the LZ1 but went reasonably quickly.  The LZ1 was with the wind and I think I worked consistently along it, swapping places with people as we had our own good and bad bits.  The drag up to Nazerth was fine, a few people overtook me but I overtook them again on the rough road (must have seen more “escaped” water bottles and broken bike bits than on any other road – it wasn’t just the water bottles that came off but the bottle carrier and the co2/spare tyre mounted to it).

Mentally I was fine. I knew I was not as quick as I wanted to be but had no chaffing issues.  I tried to eat a gel / half power bar every 20 mins but I didn’t have a clock visible so had 4 gels left at the end (so missed four).  That’s roughly 20% down on energy in.

On the ride back towards Conil (on the LZ30) I noticed that my power was down at times.  I haven’t checked that yet but I think I paced myself ok for the whole ride.  It was very difficult to resist the urge to push to push the intensity yup a bit and stay with people going by me.  I used a combination of HR and power to keep me in check. A few times I accelerated to get myself ahead of a slower rider.  On the downhills, that worked fine.  On the rolling bits on the up hills, it was probably a mistake.

Perhaps a couple of people overtook me on the last up hills and so that suggests my pace was about right.  In other words, I hadn’t slowed hugely at the end.

Wind wise, I think it was normal (i.e. windy) but I think that the wind might have started a bit earlier in the day.

Time was 6:57:48 and so pretty much in line with what I expected.

T2

Off the bike and ran really slowly with it in my bike shoes, got rid of my bike and then carried on running to my bag.  Got to the running tent and changed into a different pair of shorts and top.  Before putting the top on I got suntan creamed up, and then put top on.  A quick loo stop, and a stop for some Vaseline to help the chaffing, and I was off.

Time 9:43. Again, it’s a long run – and I changed and went to the loo.

Run

I started great.  I saw Catherine after 400m and was running at around 5:10 per km.  Hr was around 140bpm.  Great. I walked the first couple of aid stations as I was thirsty and wanted to drink enough.  Exactly as planned.

After 23 mins I started to get pins and needles and stopped after the 4k aid station to massage my foot.  I took my shoe off and an English “lady” sitting on the bench asked if I wanted her to stand on my foot.  Then she asked if I wanted her to poke a stick in my eye.  I put my shoe on and carried on, slowing a little because of the discomfort.  Soon after what would have been he turn around for the second lap, I took my shoe off again and massaged.  No better.  I ran a bit and it still felt bad.  I stopped again to massage it through my shoe, I swapped the timing chip to my right leg just in case and, again, made sure my shoe laces were loose.  After a whole I walked for a bit but no better.

I made the turn around at the end of the long first lap in 1 hour 2 mins.  I then decided that there was nothing I could do about my foot and so I would just have to bear it.  The return lap was 56 minutes.  I haven’t looked at my watch yet, but I slowed on the run back (no massaging feet though) and my Hr was lower.  I walked the aid stations getting water and the odd banana and orange quarter.  I saw Catherine at the end of the first lap and it was great.

The second lap was a struggle.  I walked a good chunk of the way.  My feet were not painful any more but I just didn’t want to run.  And when I did I was really slow.  I decided to steer clear of the fruit as it was not making me feel good, a little sick but not much.

At the end of the second lap I decided I wanted to get sub-13 hours.  11k to go and 78 minutes to do it in.  So I ran more and walked a bit less.  36 minutes on the out lap.  So that gave me the last 5.5k to do in 42 mins.  So I ran more still.  My hr was still very low and I still walked.  With about 1.5k to go I picked up the pace to 4 min per km.  Or at least that is how fast it felt.  The reality was a little different.  The run / walk took  35 mins to get me back to the finish.  Slow in real terms, but I finished.  And I was chuffed to have finished.

Time: 4:34:48

Overall: 12:52:33

So what went wrong?  If you ignore the pre-race training, nothing went wrong until the run.

The pins and needles was the first thing to go wrong.  As soon as I felt them, I saw that my pace had fallen from 5:10 to 5:30 or so per km (with my correspondingly falling).  In the past, I have managed to get my feet better again by massaging them and loosening the laces.  So I tried that twice, spending a few minutes each time. That was the right thing to do.  But it didn’t work. After that I lost the mental game.

The second lap made me realise that I was not going to blast round the course.  I hadn’t planned for mental toughness on the run.  I had planned it on the bike, but not the run.  My mind partially came back to me on the third lap.  I had a realistic goal and I worked at meeting it.  But I was not completely there as I walked long stretches.  I was lucky that the pins and needles had gone by then though.  In trying to go for sub-13 on that last lap, I had fallen for the simplicity of round numbers.  I knew I had the time to run / walk it and so did.  If at the start of the third lap I had said I wanted to be sub-12:50, I believe I would have done that too.

Also, I probably didn’t have enough proper nutrition in me.  I missed four gels on the bike (which was probably ok) but made do with oranges and bananas for some of the laps before moving back to gels.

Mostly though, my mental game for the run was not up to scratch.

Woohoo! First 180k ride of the year, but not good.

May 5th, 2013 1 comment

Ride 5 May 2013This chart shows how poor my bike training has been.

I did a 181k ride today.  Ride time was 6:45:33.  I did almost the same route in 2009 at the exact same stage of training.  Weather was similar, bike was the same, I did have an aero front wheel in 2009 though.  The course was slightly different (2k longer in 2009 where I got lost a couple of times in the New Forest).

The main difference between 2009 and  2013 was that in 2009 I had ridden my bike lots and I was highly motivated.  This year we have had quite a bad winter, I’ve been working long hours and family commitments (rugby, pole vaulting, etc) have taken up a lot of time that I could have been riding.

Adjusting for the distance, I was 9:27 slower this year. That’s actually better than I hoped. Power wise, I am 13 Watts down (154W v 167W).  I can handle that though. Not that I have much choice.    But my average HR was 141bpm v 136bpm.  So it is costing me a lot more effort to get less power.

The big difference is that my power dropped big time over the 2013 ride.  And my HR went up over the ride.

More importantly, at the end of the 2009 ride I could have run a marathon.  I am not convinced I could have done the same today.

The graph shows:

- Blue line: my average 10 minute power.  It’s all over the place because I chose a hilly route.

- A dotted blue line: This is the line of best fit of my power.  In an ideal world it would be flat.  But its not an ideal world.

- A red line: my average HR over 10 minutes.

- a dotted red line: This is the line of best fit of my average HR.  Normally, you’d expect it to go up a bit over time with constant power.

There is a metric called power:HR decoupling.  In 2009, it was 4.4%.  The lower the more endurance fit I am.  And 4.4% showed I was fit.

Today, it was 11.5%.  That’s pretty poor.  So why so poor?  I could argue I didn’t eat as much (I had 5 power bars (and some chocolate when I got water) v the equivalent of 10 in 2009) but the effect of that is probably pretty close to nil.  My guess at the real reason is the lack of long bike rides.  I did 16 rides over 3 hours between January and the IM in May 2009.  So far, this year I have done 7.  Oops….

So how much difference does a little effort make?

April 21st, 2013 No comments

IMG_3730

The picture is of Famara in Lanzarote.  The bike course comes in from the middle left (near white building), turns right in Famara and then heads towards the camera before forking right away from the beach.  It’s probably the lowest part of the course.  The course then goes uphill, and uphill, and uphill – with the highest bit about 1k away from where the photo was taken.

 

So let’s pretend I have decided what my ironman pace is.  I haven’t yet, but let’s pretend that I then ride a lap at that pace in 61:25.  Just to check that I have got the pace right, I then ride the same lap in 61:13 (so 12 seconds quicker, or one-third of one percent).  I might then check my power and find that the second lap’s average power is 1 watt less, and normalised power is 1 watt more.  HR was the same at 138bpm.  So, basically the same. Perhaps that is my ironman pace then?

So what happens if I decide to go quite a bit harder?  So the third lap is a lot higher intensity at the start and then builds gradually to “pretty hard” at the end. Not all out.  In terms of average HR, it was up from 138bpm to 155bpm (so 17bpm up) with 164bpm reached over the last bit.  Average power was up by 40 watts, normalised power by 43 watts.  The ride was the same, although a caravan did pull out in front of me while I was doing 37 kph and had to brake hard, which was a little … annoying.  Time wise though, those 40 watts saved me 5:15.  That’s 8.4% quicker.  Great.  But my watts were 25% higher to achieve that.    Doesn’t sound like a good return on my investment.

The really sad bit for me is that my normalised power was 22 watts less than I did at Ironman Lanzarote in 2009 (with an average HR of 139bpm).  And my weight is probably 3kg heavier.  Putting some numbers into a calculator suggests I’d be lucky to make 7 hours.  And that assumes I can stay comfortable on my bike.

Combe Gibbet 2013

April 8th, 2013 No comments

On Friday evening a friend told me about this as I was leaving work.  At 8pm I had spoken to the race organiser and got a place.  Beat that triathlon organisers.

I did a long bike on Saturday and then on Sunday I did a tough-ish 4k swim (including 3 fast 400m in 5:40, 5:46 and 5:55) and so am around 20 seconds per 400m slower than in 2009.  After running a few k watching the rugby I skipped off early to Overton to register (very easy) and get a coach to the start.  Getting to the coach was easy.  For the coach (with police escort) getting to the race start was a bit more of a challenge.  Some of the roads were very narrow and one of the hairpins meant all three of the coaches had to do three point turns (or more than three in the case of the first).

The coach was hot but Combe Gibbet was cold and windy.  After a short wait we started and it was a quick race down hill along a hard rutted track.

Combe Gibbet - start

 

Then I worked hard going up the hill opposite.  Overtaking some people, some overtaking me.  The paths were very compacted and lots of ruts, lose stones, etc.  Sometimes there was the odd puddle.  Sometimes a bit of grass.

After the first few minutes people seemed to stop or only gradually overtake me.  Then my feet got sore on the rocks and I twisted my ankle a little and so eased off a fraction.  People then started to overtake me gradually from mile 5 as I slowed with my feet hurting.  My shoes seemed to have shrunk as the big toe on my right foot was feeling uncomfortable.  The ball of my left foot hurt too where I landed badly on a rock.

This is around mile 5

Combe Gibbet 1

We went under the A34 and climbed up to Watership Down. Between the drink station at mile 8 to mile 12 no one overtook me (and I over took two people just before/after the 12 mile drink station) but then things started to go badly wrong.  My feet hurt big time.  Most steps hurt a lot and I was twisting my ankle every now and then.  Up a slight-ish hill on a road bit I walked.  Ten seconds later I was running again.  But it was soreness rather than tiredness.

1km from the end I twisted my ankle again and started walking up the last uphill.  This was for a long minute before the final downhill to the finish.  That last downhill hurt.  I caught one person who had overtaken me on my walk but every step hurt my feet.

Combe Gibbet - finish

So how did the race go?  Not well.  My feet hurt.  I have quite a few blisters on the toes of my feet.  And I think I will lose the nail on my right big toe.  That’s never happened to me before.  And I am still not sure what has caused that.  Perhaps my feet were swollen from the running around beforehand at the rugby, or the warm bus, or something.  Perhaps my feet have grown.  Or my shoes have shrunk.  I’ve worn the same shoes for 81 miles over three days and a 50 mile run.  I don’t think my laces were too loose.  In hindsight I wish I had worn my road shoes but I didn’t know how hard the ground was going to be and I hadn’t any time to recce the route beforehand.

I finished in 2:13.  As it was quite hilly, I was expecting just over two hours.  But I was disappointed about my pace over the last forty minutes or so of the run. The pain in my feet was the problem.  After an hour or so I would have phoned someone to give me a lift home – but I didn’t have a phone and no one would have found me anyway.

Looking at the photos of the people who were running with me at about mile 5, I lost between two minutes and eleven minutes (average six minutes).

In terms of the race organisation – fantastic! There were lots of helpful marshals, aid station staff and people with jelly babies.  Lots of signs and marks on the path for the way to go.  At the end they had home made cakes. Brilliant.

March – it’s here already

March 3rd, 2013 No comments

And I feel like I have not been out on my bike too much.  A few longer rides, but not as many as I would like.  And I’ve missed quite a few sessions (and ate really badly).

So the plan is to do every planned session over the next couple of weeks leading up to the Reading half marathon two weeks today.  And also eat properly.

The highlight of this week has been:

- to ride on my tri bars for an hour on my rollers without falling over,

- to run 20k in 1:43 on Friday morning before breakfast, and

- to run 10k on the track in 42:01 (not a PB but that’s my fastest run not in a race).

And with just under 11 weeks to go, I need more highlights.

Plan for the coming week is:

Monday:

am: 2,000m swim in wetsuit (to make sure that it is still in one piece)

Done: 30:06 for the 2k at what I think is my Ironman pace (faster at the start, then steady) plus 3 x 400m easy.  Wish I could swim that quickly without the wetsuit!  That swim has made me feel much more confident.  It’s 57:19 for 3.8k.  If I allow for a bit of slowing down then that’s still sub-60 mins.  There was little drafting in the swim as well so I think I am back on target for a good swim.
Wetsuit did has a 2cm horizontal tear a few cm below bottom of zip but should be glue-able.

pm: 7k run home

Tuesday:

am: 45 min on rollers (force)
pm: 60 min run / 12k (negative split)

Wednesday:

am: 50 min run (intervals, so tough)

Thursday:

am: 3.2k swim (400s & 800s with little rest)
pm: 60 min run / 11.5k (easier than Tuesday)

Friday:

am: 16k long run (a bit shorter than usual)

Saturday:

am: 10k run (and watching lots of rugby 7s games)

Sunday:

am: 8k run (and watching a full rugby game)

pm: 2:30 ride (with tempo thrown in)

Weight loss: 1.5kg

How fast can I run 10k?

February 2nd, 2013 No comments

IMG_3295

 

To find out, I went to Dorney Lake and did the VOTWO event.  It was two laps around “return” lake rather than the main lake.  At the start, they apologised for having to change the course, apparently something somewhere was flooded.  They did promise that it was still an accurately measured course.

It was quite cold, a bit sunny and most of first 2.5k with running with a strong tail wind.  The next 2k or so has a strong headwind, and had a slight up hill in places.  The last bit had a side wind.

For each 1k segment, my times were:

1k: 3:41, HR=168bpm (last 2 mins)
2k: 3:49, HR=169bpm
3k: 3:53, HR=171bpm
4k: 4:20, HR=174bpm
5k: 4:09, HR=173bpm
6k: 4:04, HR=170bpm (23s slower than first lap, HR shows I eased off a bit)
7k: 3:55, HR=172bpm (6s slower than first lap)
8k: 3:57, HR=173bpm (4s slower than first lap)
9k: 4:12, HR=175bpm (8s quicker than first lap)
10k: 3:59, HR=175bpm (10s quicker than first lap)

I thought that my pacing was quite good.  The first 100m involved dancing around some of the slower runners, including running on the grass a bit.  The rest of the first 1k did feel a bit easy.  I knew I was going quicker than the 4:06 per k I was aiming for but I knew I had the wind with me.  Looking at my times/HR, I did ease off a bit at the start of the second lap.

Another thing about pacing is to see how I compared to others.  Ignoring the 1st k, two people overtook me at around 2.5k, and one person overtook me at 8k. Two other people tried to overtake me at 8k but they didn’t manage it and fell back quite quickly.  I did catch one person at about 8.5k and I made that stick quite easily. So that again suggests that my pacing was quite good.

Actual time was 40:01.  Oh, for those two seconds.  In terms of VDot, it’s just about 52.

Update 3 Feb 2013: Official results are now out.  I did 40:06 per the chip.  But I started back from the front and the chip was one of those finger dab-ing ones that was after the finish line.  Ignoring the lady who smashed the world record for 10k (or just did one lap), I came 12th out of 211 people.  I was also first vet.  If I had known that, I would have stayed and got my prize.

Sensible eating starts now

January 22nd, 2013 No comments

IMG_3112How many times have I said that since September?  More than I can count.  Most of the time, like yesterday, it lasted for a few hours.  Twice it lasted a couple of days.

Anyway, I still need to get rid of a few more pounds so here goes again.

A tale of two rides

December 11th, 2012 No comments

Ride 1: 25 November 2012

Tri bike.  Strong head wind, by myself, out and back route.

80.7k, 26.3kph, Average power 166W, Normalised power 178W, No HR data (left the strap at work) but if I had to guess, I’d say 142bpm, work 1837kJ

Described the ride: “1st hour felt fine, next 30 mins, felt like power was all over the place, settled down after that. Increased effort a bit towards the end”

Ride 2: 9 December 2012

Tri bike.  Strong head wind, by myself, almost the same out and back route.  With Ashley but with almost no drafting.

79.1k, 25.2kph, Average power 168W, Normalised power 181W, Av HR=148bpm , work 1895kJ.  Average speed down a bit as stopped a bit longer part way through.

Description of ride: “With Ashley, so I went harder than wanted. Felt more pressure to push. He was much quicker on the hills but I had my tri bike so was much quicker on flats and downhills. I suffered a lot towards the end. I did pushed hard too often.”

So in summary:

- Ride 1: really good
- Ride 2: went harder but suffered at end, for a couple of extra watts.

So what was the real difference?  Let’s have a look at the numbers…

On the out bit, there was a 1 hour stretch where there were no strops, rolling hills and mostly into the wind.  I was roughly 17 seconds different between the two rides

Ride 1: AP=170W, NP=179W
Ride 2: AP=179W, NP=185W

Ride 2, I was a little bit more confident on a couple of downhills (up to 6.5kph extra).  I think I also pushed a bit harder on the downhills as well.  Another difference is that I didn’t push some of the uphills as hard as I did when I was buy myself.  For example, after I gained quite a lot of ground, I eased back on the uphills (on the way out).  So, I think on the way out of ride 2 I was more constant power, whereas with ride 1 I pushed the uphills a bit more and the downhills/flats a bit less.

On the way back, over that same 1 hour section (which actually took 53 mins on Ride 1, 56 mins on Ride 2), Ride 1: AP=167W, NP=180W and Ride 2: AP=176W, NP=185W.  So, again, I rode at a higher average power on the second ride and more evenly on the second ride.  The reason I was quicker on Ride 1 on the way back because I rode with a stronger wind pushing me along.  But those extra 9 watts or so made quite a difference between how I felt.

The attached picture shows the difference in speed between the two ride.  The blue line is Ride 1, the orange is Ride 2.  Click on the picture and enlarge it to see it in more detail.  You’ll see that some speeds do not tie up and that’s where the route was different.
