Pleasant Hill Resident Wins Thunderhill Race

Ron Gayman of Pleasant Hill captured the E3 class win at NASA’s renowned 25 Hours of Thunderhill, presented by Hawk Performance, in December.The endurance race at Thunderhill Raceway Park had nearly 50 amateur and professional race teams from throughout the United States competing. The race started on December 1 at 11am on Saturday and ran continuously until noon on December 2.Gayman’s RA Motorsports team turned 638 laps on a 3-mile long road course, logging 1,914 miles during the endurance race.

“The cool thing about this team to me is it embodies what this race has always been about,” said Crew Chief Tupper Hull. “It’s about grassroots racing, people, friends getting together, working in their own garages. Nobody has a fancy shop and a big rig. Everybody hauls the cars up themselves and works on them on the weekends to get them ready. As I’ve said before, these cars don’t win beauty contests. They win races.”

The endurance race is a grueling mental and physical test for drivers and crews. This year marked the 16th running of the 25 Hours of Thunderhill, one of the longest endurance races in the world. At nighttime, drivers just had vehicle headlights on while racing at speeds over 100 mph on the dark track. Crews were bundled up as temperatures dipped into the high 30s on Sunday morning.

“Competing in the 25 Hours of Thunderhill is incredibly challenging, and finishing the race—let alone winning—is a great accomplishment,” said NASA Vice President Jeremy Croiset. “We offer our congratulations to all of the winning teams for surviving the longest closed-course endurance race in the country.”
