Race Overview:

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

The 17th 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. 

**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!

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 event is proudly presented by Bull City Running Co
