The Mark Twain 50/100 Mile Endurance Run is in it’s 5th year. This is a 99% single track trail race held in the Mark Twain National Forest outside of Berryman, MO on the Berryman Trail located about 1.5 hours from St. Louis, MO. The Berryman Trail is a 25 mile loop that will be repeated 4 times (2x for the 50) counter clockwise. The loop starts and stops in the Berryman Campground where you and your crew/family are welcome to stay for no cost. In the 100, you can have a pacer from the start of the 3rd loop until the end. We can usually have a pacer jump in elsewhere if necessary, but like to keep it at the start/finish. We do our best to provide excellent aid and a great venue with generous time limits to provide both the most veteran of runners and first timers a great experience. We hope you join us in September!

*No Bib Transfers*
