It chronicles the experiences of 4 race teams competing in the longest endurance race in North America held each December at Thunderhill Raceway Park in Willows, California.

Sign up for the hardest race you will ever run. Just finishing this race is a victory by itself. The 25hrs will challenge you, teach you, make you better, make your team better, and most of all give you some amazing memories of a unique accomplishment.
