The Ladds 500
The following description was submitted by the event organizer.
It's spring, let's do something stupid. 500 laps of Ladd Circle is a century. Form teams of at least one person, switch riders or bikes at least 10 times during your laps, and turn left for a while. If you’re not riding, let’s party in the middle.
As always, leave no trace. Pack it in, pack it out.
