I got similar emails after indoor rides, but I am not sure I understand…
Regarding the statement “ Your threshold HR has increased by 3 to 166 bpm from 98% of 20m at 169 bpm”, was my threshold 163? If so, what is the 169 value?
you did 20min at 169bpm
The threshold is set/updated with 98% of 169 which is 166bpm
I see…hope that statement could be revised to be more beginner friendly:)
