Expect to see a lot more bicycles in Crystal City this weekend. Saturday is the inaugural Crystal City Diamond Derby.

Unlike most other bike races, this one takes place indoors at the parking garage at 1850 Crystal Drive. Both amateur and competitive cyclists will take part in events and attempt to win awards and prize money.

Spectators can enjoy a free party throughout the day at the lounge, which includes a large screen to watch the action, live music and a cash bar. An outdoor midway will be set up with vendors, food and a bicyclist sprint lane.

Activities start at 2:00 p.m., but the major competitions take place from 4:30-9:30 p.m. They’re immediately followed by an awards ceremony, then the Diamond Derby Ball which runs from 10:30 p.m. to midnight.

Although the event is free and open to the public, registration and fees are required for competitors.
