I normally run every other day and walk on the days I don't run. Sometimes I walk more than twice a day. I noticed when I last uploaded my activities that only my last run was there, not my previous 3 runs and many walks. There were only 2 weeks of activity on the watch so it is not like it was overloaded. 2 days ago I went for a run and yesterday went out for 2 walks: only my last walk was recorded. I had this problem with my Forerunner 25 and presumed it was getting old so I got an upgrade and bought the FR 35, but I have only had this one for 5 months!!! I have tried uploading activities via Garmin Connect and directly to Strava and on each occasion I lose activities. Before trying to upload them i check that they are on the watch, and they are, but once I try to upload them, they disappear. Could someone please help as this is VERY frustrating and makes wearing and trying to record activities irrelevant :/ Thank you :)
