When 24-Hours of Racing Is Just Not Enough, Sean Rayhall Enters 25 Hours of Thunderhill

America’s Rising Racing Star Closes 2015 Season at North America’s Longest Sports Car Race

Willows, California : December 1, 2015 : The standard distance for the longest international endurance race is 24-hours. So, 13 years ago, when that was just not enough to show America’s commitment to sports car racing, west coast racers invented the 25 Hours of Thunderhill presented by Hawk Performance. And, like for all of the competitors, the National Auto Sport Association (NASA)-sanctioned race is a challenge Sean Rayhall simply cannot pass up. For the second consecutive year, the elite driver among America’s rising stars travels to Willows, California’s Thunderhill Raceway joining ONE Motorsports to close his season with North America’s longest endurance sports car race. The Winston, Georgia-native, who won the IMSA Cooper Tire Prototype Lites championship in 2013 in a car of similar concept to the No. 67 ONE Motorsports Radical SR3 he will race December 5-6, is targeting another prestigious victory to add to his season tally of two Indy Lights Championship wins earlier this year.

ONE For All :

Rayhall is joined in the No. 67 by co-drivers John Falb, Todd Slusher and Jeff Shafer. The quartet performed well in 2014’s edition of the enduro of enduros, earning a podium result despite retiring early. With a year to fine-tune the prototype, ONE Motorsports returns to challenge for the ESR class win. The Las Vegas, Nevada-based group has long campaigned the popular open-top racecar with this core group of drivers. Despite his young age of 20, Rayhall is the lead driver on the effort and has been instructing Falb and Slusher in graduated Radicals for some time. The driver pairing has competed together in the highest spec-car class prototype racing, the IMSA WeatherTech Championship’s Prototype Challenge (PC) category, as recently as this October’s Petit Le Mans.

The Race :

Entering its 13th running, the 25 Hours of Thunderhill has taken on a life of its own. The race, the largest and most prestigious on the NASA schedule, has drawn 67 entries across its six very divergent classes. Cars ranging from full racing prototypes to GT entries and smaller club racing category cars make up a field peppered with professional and amateur drivers alike. Rayhall, a “Gold” level driver in the international sports car racing arena, is among the professionals who use the event as a way to get in one last “battlefield” training session before the holidays.

The Radical SR3 that Rayhall and his co-drivers will flog for 25-hours around the 2.86-mile, 15-turn track located north of Sacramento is among the quickest in the race. By design, the ESR cars are unlimited in the range of speed modifications, but must have adequate safety equipment for their speed potential. The challenge, beyond keeping the car on the track, are the differing capabilities of competing cars and drivers alike over the course of the daunting race distance.

Details :

Testing for the 13th-annual 25 Hours of Thunderhill begins on Thursday, December 3 at 9:00 a.m. Pacific Time (PT) and continues until 4:30 p.m. That schedule repeats on Friday, December 4 before qualifying sessions for the race take place at 4:45 p.m. and 5:45 p.m. the same day. The dropping of the green flag begins the race at 11:00 a.m. PT, Saturday, December 5. 25-hours later, the checkered flag brings Rayhall’s 2015 race season to a close at Noon on Sunday, December 6.
