The Phoenix Derby, featuring an open ride and several races, returns to a Crystal City parking garage tomorrow afternoon.

This year’s event, in the garage under 1851 S. Bell Street, replaced the Diamond Derby of past years, but includes largely the same activities: several underground races and a bar and lounge in the middle of the garage to watch the cyclists zip around.

Unlike previous years, all proceeds from racer registrations go to benefit Phoenix Bikes, an Arlington-based nonprofit that teaches youths how to build and repair bicycles while fostering “real-world skills and education.”

Cyclists can register to participate in the kids race, team relays, a “celebrity cruise” with an obstacle course and sprint competitions. The events start at 2:00 p.m. and runs until 6:00 p.m., with last call at the bar at 5:30 p.m. Registration for each race is $20 per rider. Spectators can watch for free.

“The Derby is a creative way to show off Crystal City’s accessibility for bicycles and cars — by highlighting the area’s often overlooked parking assets,” Angela Fox, President/CEO of the Crystal City Business Improvement District, said in a press release. “We are excited about the evolution into the Phoenix Derby and its ability to support this amazing Arlington-based nonprofit organization.”
