Feel. Your. Heart. Beat.

The most challenging Ultra Endurance Mountain Bike Race on the planet. Ok so we can't be positive that's true but we are pretty sure you will agree with us on July 8 (the day after the race).

16,000 feet of climbing in three laps in the beautiful Patapsco Valley State Park in Maryland.

  • 100 miles solo
    The pure pain epic(3 laps of the course)

  • 66 miles 2 person duo
    Sure it is going to be brutal but at least you'll be with your buddy

  • 33 miles cross country
    No walk in the park but hey at least you'll be able to walk the next day unlike some of those solo suckers

Who would do this crazy event:

Experienced MTB riders from sport to pro elites who want to crush the most challenging Ultra100 MTB course we could imagine. The 33 mile cross country event will be great for those who want a challenge but also want to be able to walk the next day.

All 100mile racers who finish the course within the cutoff time of 15 hours (6am - 9pm) will receive a 2013 Patapsco 100 Finisher's Jersey!! This jersey is not for sale and is not for anyone who finishes at 9:01pm. If you want it you are going to have to earn it.

Course Summary:

An EPIC in every true sense of the word. The course will be a 33 mile loop, 90% will be on dirt and greater than 80% will be on singletrack. This will be no walk through the park so train accordingly.
