A hot day today, 30degC in fact, did one lap around the park, and the sweat was pouring, not from exertion, but from the heat.
Also I’ve noticed. Those dips you see in the chart? They are when I’m turning a sharp corner. I guess since I’m not sprinting through the corner, the GPS logs it as a slow speed. Interesting fact I’ll have to bear in mind for future.
What’s even more interesting, is that FitBit logs the run slightly differently
You can see the dips here too, but definitely not as extreme as the one in Strava.
