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…
