Paris Marathon Race Report

Well, that's all done then...

...and quite satisfied with how things went.

The pre marathon taper held a few of it's usual trials and tribulations.  With 2 weeks to go I was scheduled to run a race of about 5 miles on the Saturday but the race choice was limited to a park run so instead I did a 5 mile 'time trial' on my own, covering the distance in 33:50.  The next day though I struggled on a 16 mile run with very tight hip flexors on the right.  A trip to the physio found tightness in HFs as well as adductors - probably as a result of almost completely neglecting strength, core and stretching throughout training and the speed training exposing it.  Took it easy as a result, dropping the last speed session as well as one run in the final week.

Carb loading was its usual challenge of bloating and discomfort and on the Saturday afternoon I was convinced I was coming down with a virus.  Ironically though, that night was the first time I got anything close to a decent night's sleep for some time.

Weight loss didn't work out as planned either in training or taper and I tipped the scales a stone over where I'd wanted to be and 5lbs heavier than Paris last year.
The forecast for the marathon was for it to be mercifully cool at 6c but there were northerly winds of 21mph gusting to 49mph also forecast, and whilst most of the route would be sheltered from these the last 6.2 miles would be in park land largely straight into the headwind.  As a result I invested in a pair of Gore arm warmers at the expo!

It was extremely cold waiting for the start, not helped by the new starting process for this year.  The normal approach has been for time based pens but this year these were also split into left and right with each half being started on a random pattern.  Unfortunately that meant a 12 minute delay before starting (as I picked the wrong half) rather than last year's 4 minutes.  The approach was designed to reduce congestion but I found the opposite to be the case as there were far more runners to pass.

I'd firmed up my plan to be:

  • Hit 20 miles at 7:44/7:45 average
  • Run the remainder below 8:02 average
It didn't take long to get into the right rhythm for that with the first 6 miles looking like...

  1. 7:44
  2. 7:39
  3. 7:39
  4. 7:39
  5. 7:43
  6. 7:37

...and nothing much to report from them other than a realisation that I maybe should have 'gone' in a bottle before we started, meaning a water station and toilet break slowed mile 7, with water stations also losing a few seconds in 10 and 13:

     7.   7:57
     8.   7:39
     9.   7:43
    10.  7:49
    11.  7:30
    12.  7:37
    13.  7:49

That meant that at half way I was feeling really good and if anything was having to hold myself back so that adrenaline didn't prompt me to abandon the discipline of the plan too much.

The next few miles were where I'd began to suffer last year but this year I just felt like I was chalking off the miles one after the other:

    14.   7:44
    15.   7:50
    16.   7:39
    17.   7:47
    18.   7:46
    19.   7:50
    20.   7:47

Not sure why I dropped a few seconds in that section.  The two 7:50s included water stations, and that area was very sheltered and briefly sunny meaning I felt a fair bit warmer but overall I suspect it was a mix of fatigue starting to kick in alongside realisation that I was comfortably ahead of schedule overall.  At 20 miles I was averaging 7:43 a mile - the average having slowed by 1s a mile since halfway.

So, that was the first part of the plan done and dusted.

   21.   7:55

No water station to mark that mile - I think it was more a case of my allowing myself to slow but still be 7s ahead of the new target, particularly as I realised I had 40s extra banked from the quicker first 20.

  22.  8:08

Over confidence, running into the wind and a drinks station all slowed me down but it was a bit of a wake up call and I decided I needed to maintain focus rather more.  This was getting tough though as at 20 miles I was starting to get some ITB pain and this had widened to engulf my quads which were incredibly painful from mile 22.

Looking at the data afterwards it looks like tightness shortened my stride but I automatically upped the cadence to over 180 spm to partially offset it.

  23.  7:51

Better, much better.  Higher cadence and a conscious effort to breathe more deeply even though it was my legs that were the challenge rather than heart or lungs.

  24.   7:49

Held the pace ok and stayed focused. 

  25.  7:44

Back to the first 20 target pace so obviously still working well.  I've since wondered whether I could have stuck to this sort of pace after 20 and whether the revised target became a justification to allow some pace drift?

  26.   8:12

Really don't know what happened there.  Certainly I was tiring and for the first time I found myself mentally 'looking' for the finish.  I don't recall the wind being any stronger but I do remember other runners were becoming increasingly unpredictable in terms of blocking my way or running erratic lines.  Mainly though I presume I knew by this stage that I was 'there' and simply lost a little discipline.

The staggered start meant a good number of runners to pass (about 1500 passed net) and that contributed to my running over distance: 26.34 rather than 26.20 and by the latter stages I was struggling to mentally factor that in.  The 250m to go mark also took me by surprise meaning I hadn't 'wound up' the pace in the last full mile.

As I tried to lift the pace in that last short section I didn't feel there was much there but the last 0.34 miles were covered at 7:01 pace so I must have had something left.

That meant I finished in 3:24:39.

A perfect 'Ronseal' plan and strategy: they did exactly what they said on the tin.

That's why I describe myself as satisfied rather than elated, but that's not to be mistaken for disappointment.  Elation would have been if I'd pressed on to run sub 3:23 but this one was just nicely executed.

Pawing over Garmin stats afterwards shows me that heart rate stayed fairly low so my CV fitness would have let me do more.  For Amsterdam I need to drop the blubber and show a bit more discipline with leg and core strengthening.  Do that, as well as run a few more miles each week and I'm confident of getting under 3:15 but for now there's no running planned until next week at the earliest!

I think the main difference between this year and last year's Paris marathons is the lack of anxiety you seem to display this year. I'm really impressed with how you've overcome your, forgive me, a little neurotic approach to training.

Congratulations on such a great time and all the best for Amsterdam!

Well enjoy the rest this week- you have certainly earned it. Glad that the training plan worked so well for you too. Hopefully you can get that elation in Amsterdam.
