Join the excitement of this year’s “25 hours of Thunderhill” by pledging to support Racing Team Semper Fi, who will donate every penny pledged to the Injured Marine Semper Fi Fund!

Sanctioned by the National Auto Sport Association (NASA) and co-sponsored by the U.S. Air Force, the “25 hours of Thunderhill” is known as the ultra marathon of road racing requiring a well-prepared car, highly experienced drivers, endurance by all and some luck.

While more than 80 teams are expected to compete in this year’s race, the Racing Team Semper Fi race car will be the one to beat in this nail-biting event that holds unexpected turns for all those involved. Held at the Thunder Raceway, a 3 mile road course in Willows, CA about two hours north of San Francisco, the race will host teams consisting of multiple drivers, up to eight crew members and up to four support staff.

Our team will be racing one car and switching drivers.
