So this is my 5Km run from home. It's up and down, and quite a challenge, some places very steep. It's an out'n'back road course, and I think it's pretty good for training for Parkrun.
So today I set off (north on the purple - done by hand in GIMP, hence the wobble), I checked that Garmin had the GPS signal and started it recording the run. After a few seconds I checked to see that it IS running, and the time and pace is about right - and it was. So then I forgot about it until the point (Green Blob) which is exactly 1Km from the start. I have loads of runs on this route and it always records 1Km there. Only today it didn't. Nada, nothing, not a dicky bird. The damn thing had stopped recording and not even recorded the bit at the start that I checked it had been doing. So I started it again and ran on. The Green Blob is the start as far as Garmin is concerned.
Does anyone have any idea what I did wrong? If I had clipped the button, I'd expect it to be in Pause, but it had gone right back to watch-mode. This isn't the first time this has happened, and if it's me, I'd like to know.
