I don't get the time to ride as much as I'd like I typically ride once a week by myself on neighborhood streets. I average mid to upper 16.xx mph on those rides that average 30-40 miles. In groups, I tend to be a bit faster. I assume it's just some sort of competitive mentality. I accidentally ended one session and started a new one on my 810 after 37 miles, so the ride showed up as two rides. So, I had to do math to come to the 15.7 mph average. I also suffered a bit from not really knowing a proper technique for getting up the hills. I just dropped the gears and spun. I felt I had plenty of energy to go, but my quads just did not like the hills. It probably had to do more with technique.
