After 5+ years of reliable use, marathons, half-marathons, half-ironmans, surfing, skiing, biking, and hiking, my Forerunner 935 is appears to have broken the seal swimming last night. No problems yet but it went from nothing to looking like a big deal. I have had my next Garmin picked out already (epix gen 2). The problem is, my race is in 11 days and I leave in 7. Will this last? Should I try to get one rushed? Any advice?
