Here's an Endomondo log of the ride.
- Distance: 4.77 mi
- Duration: 31m:21s
- Avg. Speed: 9.13 mph
- Max Speed: 19.34 mph
I started the ride at 91% battery, and finished at 17% battery. That's 74% battery usage for a 4.77 mile ride, and figures out to about 6.5 miles of total range, which is near the upper end of the "5-7 mile" advertised range.
I was riding in "Mission" mode for the whole race. I did the opposite ride (downtown to their office) immediately before the race in "Delirium" mode, but I wasn't trying to go as fast. For some reason I was getting serious foot fatigue on the way there. I thought maybe somehow it had something to do with the mode, which is why I switched to Mission for the race. I didn't experience nearly as much fatigue on the ride during the race, but I have no idea if it was related to the mode or something else.
