A clockwise day-long ride around the four corners of our fair city. 
No pre-registration, no fees, no tyvec numbers, no support vehicles, no reason but to ride.

Not a race, but not for beginning riders. We ride Critical Mass style with mutual support and no drops at a reasonable pace. An excellent first timer's century ride with dozens of public transit bailout points should you feel the need to split early.

Begun in 2001 by John Greenfield, who led it for 10 years, Chicago Perimeter Ride continues through dozens of neighborhoods and a striking variety of scenery. The Best Ride of the Year!

Bring cash for meals, some extra tubes to share, and plenty of water. We leave Buckingham Fountain at 9 and regroup at the South Shore Cultural Center before heading to the wilds of Wolf Lake, beers in Pullman, ice cream in Beverly and on and on.
