Rides are "rated' from a 1 to 5. Distance & difficulty of rides increases. A 1-ride is a short, flat-ish ride, 25-ish miles. A 5-ride is longer (80+ miles) with much more climbing.
Pace is determined by who is riding. But, there are multiple levels of riders on each ride: fast to slow. Just a matter of finding your group to ride with.
Each ride also has a cue sheet for you to print out & carry with you so you don't get lost.
Have fun.
