About the Event
This is the 17th annual Mountains-to-Sea Trail 12M & 50K Challenge, a trail race scheduled for a spring date. The event takes place in Durham, North Carolina, starting and finishing at Riverside High School. It offers two distances: a 12-mile run and a 50-kilometer run.
Course Details
Both courses follow the Mountains-to-Sea Trail (MST) on single-track trails through the woods along the Eno River towards Falls Lake. The courses are updated for the 2026 edition due to construction at Blue Jay Point County Park. Updated maps are to be posted on the race site.
Event Information
The event is a cupless race, meaning participants are asked to carry their own hydration device. Water and electrolyte drinks will be available at all aid stations and at the finish area.
All participants receive a custom race shirt, a finisher's award, and refreshments at the finish. Additional awards are given to the top three overall finishers (male and female) and the top overall masters finishers (male and female) in each race distance. Visit the organization's website for the most recent information.
