Does anyone know if you can delete part of the data on the GW-60 watch, yesterday i turned watch off as normal after sesion and put watch in clothes bag, somhow it either did not turn of or turned its back on and recorded jouney home and so can not add my results of the day on here via this watch.

Sorted out myself via GPSResults, able to upload and then delete part of tracks did not need, phew ??
