About
The Tuesday Night Thunder Race Series offers weeknight criterium bike racing in Louisville, Colorado, held on Tuesdays beginning in June. Sanitas Sports coordinates the series, focusing on the local racing community. Its format is designed for amateurs, professionals, beginners, and anyone seeking a swift midweek road race without complex logistics.

The TNT lap measures 0.6 miles with 27 feet of elevation gain per circuit. The course features three wide 90-degree turns, followed by a long, gentle uphill turn leading to the start-finish line. This layout is accessible for novice criterium racers yet allows skilled riders to exert maximum effort. Race numbers are affixed to the right side.

The series is presented in partnership with HUNT Wheels and Louisville Cyclery, with an stated objective of linking bike racers to the local community.
