HOWEVER, I felt like everything went to plan except for two sections. Looking back through my data, those two sections do stick out at me and I’d like to show them to you.

Here is the raw output from TrainingPeaks, the software I use to analyse training files. To the untrained eye, it may look like a bit of a mess, but with a little background information, you can unlock a world of information. I’ll show you.

First, if you clear out some of the excess data and only show heart rate and running power, you can see that I slowed down over the duration of the race.
The rate at which I slowed down fits nicely into the results published in a 2004 study titled “Changes in Running Speeds in a 100 km Ultramarathon Race” (read here).
The researchers showed…
