The Dirty South Roubaix

The Dirty South Roubaix is for you if you are looking for an awesome route, a challenging course, killer scenery, beer, food and cool friends to hang out with for a day. Their 100k+ is the main event of the day, but they also offer a shorter course for anyone who doesn't want to tackle the full 100k. The short course is near half of the 100k. Don't worry, it will still have a few hills and plenty of gravel.

The Shippey Endurance Runs

The Shippey Endurance Runs is STL’s Original 100-mile trail ultra! Nestled quietly in the rolling wooded hills just outside of Greater St. Louis lies the wonders of the Beaumont Scout Reservation.
