I am still thinking how did I run a minute faster than my normal 10K time on yesterday race.
It was an out and back course. The map showed km 4 to 5 is shorter than km 5-6, where the turn around point was. I don’t think I cut the course, because I definitely turn around at the cone.
The turn around might have thrown off my gps watch.
I think on the second half I ran faster because it was down hill. I have not done the split yet because my watch was wrong (I think), so its data can’t be trusted.
Here is the elevation profile.
