interesting jump in heart rate at 4km
is this for a virtual 10k race?
Weekly Strava challenge with my neighbour. Different run each week. So far its Tim 3, Dave 0.
Using my garmin data analysis skills, I would suggest its an anomaly, if its not using a strap and the wrist HR
I'm more impressed by the 180 degree turn at 16:55 while maintaining a sub 4min/km pace.
Panicked u-turn in a dead-end street! Agree with Tane's comment on the dodgy nature of wrist HR.
