TNT Tuesday Night Thunder Race Series 2027

TNT Tuesday Night Thunder is a weeknight criterium series at The Pro’s Closet in Louisville, Colorado, with racing on Tuesday evenings through the summer. The format is short, fast bike racing on a closed lap course, with A, B, and C categories so newer racers and stronger riders are not all thrown into the same field. Sanitas Sports runs the series with a community-first aim, and the listed races are USAC sanctioned, presented by HUNT Wheels and Louisville Cyclery. The lap is only 0.6 miles, so riders see the same features again and again: three wide 90-degree turns, then a long gradual uphill sweeper into the start/finish line. Each lap gains 27 feet, enough to make repeated accelerations hurt without turning the race into a climb. The series draws up-and-comers, local pros, and occasional WorldTour-level riders, while the low entry price and free listed starts for women and juniors keep it accessible. Race numbers go on the right side, with registration and parking handled by Tendeg LLC.
