About the Tunnel Hill Marathon
The marathon is a distinct Saturday distance within the Tunnel Hill ultra weekend. Its current course turns south from Vienna and finishes before the namesake tunnel used by longer races.
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.
