AdventureCORPS, an event production firm specializing in ultra-endurance sports events, will host the 31st Anniversary of The 508 Bicycle Race on October 4-6, 2014. Founded by John Marino in 1983 and known as "The Toughest 48 hours in Sport" and "The Great American Bike Race," it is the world's premier ultra cycling race. This 508-mile bicycle race is revered the world over for its epic mountain climbs, stark desert scenery, desolate roads, and its reputation as one of the toughest but most gratifying endurance challenges available, bar none. Solo, two-person relay, and four-person relay divisions are offered with a field limit of app. 250 racers (app. 80 soloists and 65 relay teams). The 2014 race route will be unveiled in early- to mid-April, then registration will open three days later. Please feel absolutely certain that the race will be held October 4-6, 2014. Entrants will have six months from entry to start line, so please be patient and know that we appreciate your support! (Click here for the full statement and update.)

New for 2014, "The 308" We are pleased to offer a 308-mile ultracycling extravaganza from Santa Clarita to Trona and back to Santa Clarita: an epic race from the Los Angeles basin through the Mojave Desert on May 31 - June 1. The route is based upon the wildly successful abbreviated route used for the 2013 edition of The 508 which had to be shortened due to the U.S. government shutdown. More info. Entry open now!
