I read those ride descriptions. I feel that the advanced level ride would be more to my liking, just don't want to play hike-a-bike games. I'm riding fully rigid bike, and while I've done 22 mile rides with 10+ miles of climbing and 2.5-3.5 thousand feet of elevation gain, the time to miles equations still doesn't compute in my head. Those rides I've done in like 3 hours. Just don't want to hold up the groups, or wished I had gone with a different one or some such bidness. I'll figure it out once I get up there I guess.
I was thinking the same thing I want to try at least one intermediate ride...
