The Bailey Glasser Boise Twilight Criterium, celebrating 37 consecutive years of crit racing in Boise, is excited to welcome thousands of racers and spectators to downtown Boise on Saturday, June 29, 2024. Presented by Lactalis, the longstanding Bailey Glasser Boise Twilight Criterium is proud to be part of the American Criterium Cup (ACC) series, which brings together the fastest riders and teams in the country (and beyond) to compete for a combined series purse of $500,000, split evenly between women’s and men’s fields.

The ACC highlights the top 8 iconic criterium races through 8 different states in the US.

In addition to a day of men’s and women’s professional cycling road races, local fans can expect an enhanced ICCU EXPO park opening at 1:00pm, with a local and regional beverage garden, vendors, food trucks, activities, and the best view of the races!

NEW THIS YEAR we will kick off the cycling weekend with the Lactalis Twilight Kids Bike Rodeo at College of Western Idaho in Nampa on Friday, June 28.
