(We have 3 Swifties certified and 2 more in classes this 6 weeks.)
Just an FYI - There are more spots open in the 6 & 8 pm Tuesday night "Intermediate" Classes. If you can do our groups ride with echelons, you can do the Intermediate Class. It's a 6 week class, you can still jump in on the second week. Free Rental Bikes with class. Just bring measurements and pedals. Also classes on Thursday and Friday at 6:00 and weekends.
see http://boulderindoorcycling.com/ - Call them for more info. They are bad with email and updating website...
It's fun and indoors. No wind, rain or snow!
