Using my FR245 displaying speed, time and heart rate on a kayak in a time trial.
After about 5min of working fine, the speed changed to zero (0.0). I thought it had lost GPS or paused but the other fields continued to update and the watch continued to show auto-laps every 1km so the GPS was evidently working. Speed annoyingly stuck at 0.0 for the remaining 50min or so.
I downloaded the activity after and looked at the file and it exactly reflects what I saw: at each trackpoint position and time (and heart rate) are correct but after about 5 min of correct operation speed is recorded as 0.
The zero speed in the file gets masked by any software that recalculates speed based on position and time so looking at tracks on the map it isn't obvious.
Has anyone else experienced this? My kayak profile customised from a copy of a run profile.
