TNT Tuesday Night Thunder Race Series

Tuesday Night Thunder (TNT) is a Tuesday-night criterium series in Louisville, Colorado, beginning each June. Presented by HUNT Wheels and Louisville Cyclery, it focuses on short, fast weeknight bike races instead of a long road course. Some event listings indicate USAC sanctioning, while others state they are self-categorized and unsanctioned; riders should verify the current registration page before entering. The TNT lap measures 0.6 miles with 27 feet of climbing per circuit. The course features three wide 90-degree turns followed by a long, gradual uphill sweeper leading to the start-finish line. This layout is accessible for beginners yet allows experienced riders ample opportunity to compete intensely. Women and juniors participate without charge, race numbers are affixed to the rider's right side, and Tendeg LLC manages registration and parking in Louisville.
