Yokohama is sponsoring the two drivers in the contest, which runs 4 to 11 May, and Subaru Motorsports will provide a pair of WRX STI Type RA vehicles for a head-to-head showdown.

Nitro Circus ringleader Travis Pastrana and fellow Nitro Circus member Blake 'Bilko' Williams, both Team Yokohama members and the winners of last year's Stock Touring division in a Subaru WRX STI, are back again, with a twist. This time, instead of being teammates, Pastrana and Williams are taking each other on in the eight-day, 3,379 mile (5,438km) race.

"The WRX STI Type RA was designed to be track-ready without sacrificing comfort for the street," said William Stokes, Motorsports Manager for Subaru of America. "With One Lap demanding both serious track performance and long-distance highway driving, Travis and Bilko will definitely be putting their cars to the test."
