Mountains-to-Sea Trail 13M & 50K Challenge

2027 Registration will open on 12/1/26 at 8am EST!

Join us for some beautiful spring single track trail miles along the MST!

The 18th annual trail race will follow the beautiful Mountains-to-Sea Trail (MST) as it winds through the woods along the Eno River towards Falls Lake. 

Not planning to run?

PLEASE SIGN UP TO VOLUNTEER! We need you! Thank you 🙂

**2027** Race will again be held at Riverside High School
MST 13 Miles
MST 50+ KM  (Closer to 31 miles)

All participants will receive a custom race shirt, finisher's award, and plenty of refreshments at the finish line!  You can expect that we will setup a well-marked course, well-stocked aid stations, accurate results, and a good time! We will do our best to make sure you enjoy your experience!

MST 13M & 50K will be cupless! In an effort to make this a greener event, we ask that participants carry their own hydration device on the course. Water and electrolyte drinks will be available at all aid stations and the finish area.

All participants will receive a custom finishers award, plus additional awards for the top 3 overall finishers (M&F) and the top overall masters finishers (M&F) in each race.

This is a trail race: very different than a road race. You will be exposed to many obstacles you would not normally see in a road race. The course is a single-track hiking trail, so there are roots, rocks, quick turns, logs, woodland critters, and possibly water to avoid. There are plenty of aid stations and volunteers on the course, but if it’s a hot day or if you think you need more fluids, we highly recommend carrying your own.

We ask that you do not run with your dog, run with an unregistered pacer, run with headphones (open ear such as Shokz are OK), run with a jog stroller, and, of course, do not litter on the trail.
