I had a race today and to my surprise my watch started acting really weird halfway through the race.HR was jumping from 70bpm to 180bpm, pace was all over the place ( it’d range from 04:40 to 7”/km in a matter of seconds) and it didn’t record the last half of the track.
it was very upsetting. I was relying on the pacepro pacing strategy and everything when to ***… ( i did improme my time thou 
)
Did anyone have a similar problem? Any idea on how to fix it?
thanks a lot
