CHICAGO — If you want to avoid seeing nude cyclists jiggling through the city streets, avoid going outside at several spots along the Naked Bike Ride's route on Saturday.

But if you want to join in, here are the official details on the "bare-as-you-dare" 14th annual group ride, set to start around 8 p.m. Saturday.

The ride will last for 14 miles before ending around midnight, organizers say.

In previous years, the group of about 1,500 riders — escorted by (uniformed) Chicago Police bike cops — has rolled down the 1500 block of North Milwaukee Avenue around 11 p.m.

The event kicks off in the West Loop at an undisclosed location. Cyclists interested in participating can check out the Facebook event page for details.
