52, 6'3" in the morning, 204 lbs today.

My last 8 decent rides average including stoppage was
10 mph over 630 miles
15.3 over 135
14.3 over 186
14.5 over 124
14.1 over 135
13.1 over 124
14.8 over 135
13.4 over 135

The 135 course is pretty much dead flat, the 630 and 186 were hilly. Not fast in anybody's book, and I waste too much time in stops.
