2025 Boise Twilight Criterium

The Bailey Glasser Boise Twilight Criterium celebrating 38 consecutive years of crit racing in Boise is excited to welcome thousands of racers and spectators to downtown Boise on Saturday July 19 2025. 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 split evenly between women’s and men’s fields.

The ACC highlights the top 6 iconic criterium races through 6 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!

Back this year prior to the Opening Ceremony – join us in a one-mile fun run on the course benefitting Girls On The Run (pre-registration required).
