There's always the group hill ride on saturdays that the Ophirs do from the Coffee Republic parking lot. Leaves at 8:30 a.m. w/ 35-45 mile options. I do variations of the same ride on sundays too. There are lots of options to change up the ride w/ other climbs to keep your interest "peaked" (oh I'm sorry about that one!)

I will forward you the site for the folsom peloton group too! Hope to ride w/ you soon!
