Mountains-to-Sea Trail 12M & 50K Challenge

Race date: APRIL 13, 2025

REGISTER HERE! [Registration will open on 12/1/24 at 8:00am EST.]

Join us for the 16th annual MST 12M & 50K Challenge! The race course will follow beautiful single track of the Mountains-to-Sea Trail (MST) as it winds through the woods around Falls Lake in Raleigh, NC.

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!

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, run with a jog stroller, and, of course, do not litter on the trail.
