Trailway Trail Race
The Trailway Trail Race takes place on October 10, 2026 at Lake Somerville State Park, Birch Creek Unit. The event offers multiple distances along the park’s Trailway, a route that links two park units and follows much of the lake shoreline.
The course is a lollipop style loop that alternates between open shoreline and fully canopied forest. Terrain is mostly flat with gentle rolling sections, hard packed rooted areas, and patches of sand or loose soil. Rain can create wet or flooded sections; sunny conditions expose runners to lake views and a beach at the finish area. The start and finish sit on a lawn at the lake edge.
Distances:
- 50k trail run
- 26.2 mi trail run
- 13.1 mi trail run

Course markings include orange caution tape, yellow arrows, and confidence markers; signs at junctions indicate distance-specific turns.

Drop bags are allowed at aid stations except Wolf Pond. Chip timing is used with ankle-worn chips. Pacers are not allowed.
A pre-race tailgate will be held the evening before. Camping is available in the park. The ruck division has mandatory weights based on body weight, a required weigh in, and specific equipment rules.
