The Boise Twilight Criterium is one of the top road cycling races in the United States. This criterium races through the streets of Downtown Boise with the start/finish line sitting just feet for Idaho's state capitol. The race is one of 8 criteriums on the American Criterium Cup (ACC) which was originally conceived in 2022 as the premier criterium series in the United States. 

The series, which has partnered with USA Cycling to serve as the premier professional road race calendar in the United States, will see a total prize purse of half a million dollars divided equally between genders across the series races with $100,000 of winnings awarded to the top team and riders in the final ACC standings.
