I wear my Garmin sometimes. It's quite fun to see how far you have ridden and how far upwind you get on a run.
Normally I am in too much of a rush to stuff around with the GPS but I have been cycling to work and use it as my speedo so I now have it with me all the time. It's just a big watch so it's no hassle to deal with.
Last time I did it I did a 4 km upwind run with heaps of wave play on the way back.
Total distance 53.69 km
Total time 2:17
Max speed 41.4 kph
Average speed 23.4 kph
Average upwind leg: 500 m
Average upwind ground: 250 m
Best upwind gain 450m
I can't see the jumps in 3D but I didn't do much jumping that day.
This is just the upwind run. The later runs were too squiggley to be of much interest. You can see at leg 7 where I ran back downwind to wait for my mate.
