Not planning to run?

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

**NEW FOR 2026** We are updating the 12M and 50K courses due to construction at Blue Jay Point County Park. MST 12+ Miles (Closer to 13) MST 50 KM

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 12M & 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.
