Get ready! This is where things get a little ridiculous (in the best way). Our costume relay is equal parts teamwork, laughter, and questionable fashion choices. You’ll tag in, suit up, and sprint your heart out. All while wearing something you definitely wouldn’t choose for speed. It’s chaos. It’s joy. It’s a crowd favorite for a reason.

• When: Saturday, July 18 @ 2:30 p.m. with a pre-race costume relay and race overview.

• Teams: 2-4 people per relay, 24 teams max

• Format: Preliminary heats with single-elimination to advance to the championship final. Each race is 4 laps, and each lap is a half-mile. Up to 6 teams on course per race, depending on final team count. No rider may complete more than one consecutive lap. There must be a handoff after each lap. The course will be on the New Belgium Brewing short track. Course map will not be provided in advance.

• Costumes: Make it fun. Make it freaky. Make it yours. The only rules are that you must wear a helmet and your costume must not impede your visibility or ability to ride. Birthday suits are not a costume option.

• Prizes: The championship team and crowd-determined best costume will receive a gift card to Rio Grande Mexican Restaurant.

• Registration: Opens on June 15 on BikeReg. One registration per team. $50 per team entry. All teams must include a team name. Waivers are required for each rider.
