SoCal Endurance, the organizer of the 12 Hours of Temecula and SoCal Enduro endurance series races, is adding a mountain biking marathon and adventure run to its events lineup this year.

The SoCal Fat Tire Epic 50, a mountain bike marathon race that bridges the gap between endurance and cross country racing, will return this year on Saturday, February 9. The course consists of two laps of 24 miles for most categories, with long climbs and twisty, roller coaster downhills.

That same weekend, SoCal Endurance will host the Temecula Adventure Run, featured races of three different distances for all levels of runners.

“We use to run the mountain bike marathon in October, but we stopped in 2010 because it was always too hot,” said Jason Ranoa, race director for the events. “We’ve brought it back in February so it will be very comfortable. The running race is something we’ve always wanted to do.”

SoCal Endurance will also host its popular mountain biking race series, Twelve and Six Hours of Temecula and SoCal Enduro. Each series of races takes place at Vail Lake Resort and features three events that take place throughout the year.

Ranoa said his events team is designing new trails and courses for the 2014 races. “Over the off season we’ve really been pushing creativity,” he said. “The SoCal Enduro series is really taking off. Enduro MTB racing is the hottest new form of racing. It combines the technical riding of all Mountain and the fitness of cross country. Last year we had over 4000 racers participate in all the race’s we hosted, and we expect more in 2014.”

Here’s the schedule of all the events SoCal endurance will host at Vail Lake Resort:
