I did some running sprints today. I hadn’t been doing enough consistent running during the summer to feel confident that would go well, but with the change of seasons, I’m running more. It went fine other than being very tiring. No pain or problems.

Edit: I went back and checked the data and Fitbit thinks my HR went just above 190 on several of the sprints. I guess I’m not surprised because it felt strenuous.

I don’t usually sprint on Sundays, but it’s really spectacular today and above 50F so I was thinking of also doing a ride on the Katy so I didn’t want to do a longer run.
