I rode Riley on Sunday, in 91 (99 "realfeel") temps. Had a good ride but I really have to bring it to get good work, and we DID work. My Fitbit tends to underestimate my heart rate. I ran a 5k the day before, and pretty much went at the top of my ability (struggling mightily at the end) -- my peak heart rate was 181 bpm.
