I just got back from RAGBRAI 2016 and went to upload all 7 days of riding from my older Garmin edge 305 to my computer so I could upload to strava. I noticed that day 1 and 2, even though still on my unit with miles and stats in the history, was blank when I uploaded to strava. Apparently the device ran out of space and over wrote the first 2 days. I keep the unit cleaned out so it had no other history in it prior. Is this what I can expect in the future until I can afford to upgrade? I guess I could have taken my lap top along and tethered it each day then deleted my ride from the unit. Suggestions?
