I use Strava as one of the environments that let me analyze the rides I do. I find very useful the kudos system, the way to show the data, how to compare with yourself, etc.
Yesterday I took my bike in Sevilla. It was October the 1st but there were around 35ºC at 17.30 that was the only slot I had to take the bike.
I did a route that I use to do, and the feeling of doing this route with such temperature is very different than when you perform it at 20ºC.
I understand that the effect of heat in every person is different, it’s also different for a single person depending of other factors. But in general, the effect of the heat reduces the performance of the workout.
For instance, the performance I had yesterday was very different in the first part of the ride than in the second part. Basically the difference was:
- First half: speed = 2:31 min/km
- Second half: speed = 2:45 min/km
The reason was not the slopes or the excessive speed during the first half, it was the temperature that provoked me to burn down slowly. The hot wind did not help either, in any case the effort done was useful for my goals, to suffer during the bad days is also a useful training for keeping the mind concentrated and minimize the lose of time.
I would suggest to Strava to add this variable in some type of kudos, or as a separate factor to measure.
