I just started riding and logging my miles in May. My terrain is rolling hills.

I ride 20-30 miles a day on the weekdays averaging 18-19.6 mph by myself.

Group ride on Monday is 28 miles, and depending how many people come and which group I end up with, we average 20-22 mph.

I have taken some longer rides on the weekends 43 miles at 18.6 mph, 33 miles at 19.2 mph, and 55 miles at 17.5 mph.

For next weekend's century, my first, I am hoping to be in the 15-16 mph range.
