What began as a simple idea between three friends in 2003 has blossomed into not only a great event for avid motorcycle riders, but also a tremendous charity fund-raiser.

Jere Starks, vice president of facilities at Infineon Raceway in Sonoma, joined with friends Jim Randolph and Jay Brosius to create the "3Js Motorcycle Days" back in 2003.

To date, the events have raised more than $70,000 for Speedway Children's Charities, the charitable arm of Infineon Raceway. All proceeds benefit qualified youth groups in Sonoma County.

The trio branched out in 2005 & 2006, hosting a "3Js Motorcycle Days" event for AMA rider Vincent Haskovec, who sustained serious injuries resulting from an accident during an AMA event at Infineon Raceway. The special events generated $140,000 for the young rider.

"This began as a simple idea but it's really turned into something special," Starks said. "What could be better than running one of the best road courses in the world for a day, and at the same time, helping a charitable cause? It's a great deal."

The days are spectacular on Infineon Raceway's twisting road course, as riders get ample time navigating the circuit, with safety always the top priority.   The best part is, nearly 100% of your entry fee goes directly to charity.

It's an event for riders to casually ride the road course, mingle with one another and just enjoy the day, which also includes:

• A tasty catered lunch
