The Infinity Run
Infinity Run Colorado is a unique endurance challenge where participants run one mile around the Pikes Peak International Raceway track every 20 minutes, starting at the top of each interval. The event continues indefinitely, testing stamina, strategy, and mental resilience until only time decides the finish.
Bataan Death March Colorado
A powerful tribute to the 15,000 American and Filipino soldiers who lost their lives during World War II's Bataan Death March. This event isn't just testing the participant's physical limits - it's a tribute to heroes.
