The first race in the Ridin' Dirty Endurance series, "Sick 6", is a 6 hour endurance race held at Lake Thunderbird in Norman, OK. This trail features 6 hours of smooth switch-backs and flowing single track at non-stop, break-neck speed. So much pain and so much fun, there's only one word for it...Sick!
Our second race, "Six in the Sticks", will be held at the technical trails of Turkey Mountain in Tulsa, OK this Fall. Turkey Mountain is one of Oklahoma's most technical trails. This year's race will be technical and there will be NO ROAD SECTION this year. So bring your skills... all of 'em.
Our final race, "Broken Nose 50", is a 50 miles race held at Roman Nose State Park in Watonga, OK. This course is packed with wicked climbs, fast descents, and stellar scenery. Something is bound to slow you down at this race. Rattlesnakes, cactus, and dehydration are amongst the culprits. This has been Oklahoma's most popular endurance venue for the past 5 years. The Broken Nose 50 race staff puts on a great race that keeps endurance racers coming back for pain filled smiles, year after year.

Whether you're racing for the crown, the challenge, or the fun, you'll need to pack a lunch if you want to compete in Oklahoma's only USAC Marathon Endurance Championship!
