About the Tunnel Hill Marathon

Course
Runners head south from Vienna on the Tunnel Hill State Trail, turn, and return for a certified 26.2 miles. Crushed limestone and a shallow rail grade support even effort.
Race-day weather
November can be cold, mild, wet, or windy. Rain softens the trail surface, while fallen leaves may hide small irregularities underfoot.
