This is what I did in the lab tonight - science!
And this is the first 4 hours of Sunday's ride. My GPS ran for 4 straight hours without shutting off, so I think I may have fixed the problems in my etrex Vista unit with a little surgery. These things are horribly unreliable on bikes and motorcycles when the going gets rough. Think twice before buying one, because Garmin won't even admit this issue is a recurring problem. A quick survey of the internet message boards clearly states otherwise.
And here are the stats for February:
Hours on the road bike: 20
Hours on the mountain bike: 43
Hours on the 'cross bike: 4
Hours of skiing, hiking, or climbing: 24, all hiking
Total hours in the saddle: 67
Miles covered: 672
Total vertical gain: not calculated
Problems with the body: minor pain at base of left quad after many hours of hard climbing
Problems with bikes: 7 flats, 2 dead road tires, 1 dead Campy Chorus shifter, 1 dead Crank Bros pedal, 1 worn out chain, 1 pair of mtn bike shoes with stitching blowing out
