take it back gavin, it's obviously not working properly. i got a garmin forerunner 101 2 weeks ago, no problems so far. other suggestion is to take batteries out when not in use, sometimes simple ideas are best......
My first 10k and a time of 48mins. I'm pleased to have completed it, but hoped to beat 45mins, as I have done in training. Well organised race, very worthwhile cause, nice flat course, would definitely run this again. Thanks to everyone who helped with the organisation of this race. My next big race is a HALF MARATHON in November. Any tips?
