I did z Thursday Ride yesterday. Just 1600 feet of climbing and 38 miles. Average moving speed was 10.6 mph according to the Garmin. Now on a flat ride my averages are usually around 11.5 and I simply cannot understand how people are reporting 18 and 20 mph averages..
As far as 11 mph range, I'd do a 41 mile ride with 5,000+ ft of gain to slow me down to the 11.1 average range. Not bad for a 240 pound rider eh?
That's what I like about Strava and videos, they don't lie!
The video of the climb with my buddy Ron. I outweigh him by 70 pounds.
