Today I had a lot of fun in a masochistic sort of way!
Starting out, I took it nice and slow – keeping a sensible pace. For the first ten kilometres, I was enjoying playing the running tourist, taking pictures of the crowds supporting the runners as well as the sights visible from the road. I will post some of these pics in a later blog.
The temperature didn’t reach the 11 degrees that the forecast promised us. In fact, it was pretty chilly and rained two or three times during the race. But this for me was a good thing.
Looking at the splits for the whole race downloaded from the official website, we can see that my pace was very consistent throughout. Split times refer to the time measured from the start to a given point along the way, while lap times refer to increments within the race. Except for the first 5k and the last 5k lap (35-40k), I managed to run each kilometre in less than five minutes.
Here are the times laid out in a chart:
Graphically, with the y-axis set to between 4 minutes and 6 minutes, you can see the consistency of the lap times in the middle of the race. Evidently, my split times got faster on average as I went through the race. This is because I sped up somewhere around 8 or 9 kilometres and held my pace consistently for most of the rest of the race. This had the effect of canceling out the slow start. As we approach the end of the race, you can see the split time starting to go up slightly as I got tired. I don’t mind admitting that resisting the urge to walk was quite a battle of the conscience!
Over 42.195 kilometres, even a few seconds per kilometre up or down on average pace makes or breaks a full marathon. Today was my best ever time by about 6 minutes. This translates to around an average 8 seconds per kilometre quicker than last year’s Tokyo Marathon. It took me 4 minutes 54 seconds to run a kilometre today, while in Tokyo it was about 5 minutes 2 seconds. It just goes to show that every second counts.
