Littleton Twilight Criterium & Bike Fest

What is a Criterium?

A criterium is a bike race on a short, closed-circuit course, usually under a mile in length and lasting 30 to 60 minutes. Criteriums are great fun for spectators because you can walk around the entire course and see racers fly by every few minutes at nearly 30 miles per hour, in very close proximity to one another!The Littleton Twilight Criterium takes place on the streets of Historic Downtown Littleton with lots of corners, speed and action on the 0.8-mile course, and and featuring many of the best racers in the nation! The event is part of both USA Cycling’s National Calendar, and the top-level USA Crit Series. There will be seven races and a Cruiser Ride (open to the general public), highlighted by the men’s and women’s professional races under the lights.

Littleton Twilight Criterium joins USA CRITS  Series

USA Crits logoCriteriums are America’s most enduring form of bicycle racing, transforming vibrant downtowns into world-class cycling arenas. Unlike other professional sports, bicycle racing in America has no ticketed income source, and unlike running or triathlons, no large participation base to fund the events and athletes. The sport can only grow through an increasing number of fans and a vehicle to support this growth. Like the creation of the USA CRITS Series, races are born from event directors’ passion for the sport.

Watch the Littleton Twilight Criterium and more than 20 other days of live streaming while supporting our event and increased funding for teams. Help make racing in America more sustainable by joining and watching live criterium racing while supporting our event and increasing financial support and promotion of teams.
