Tough as Trails Race Series

Bull City Running Co. organizes the Tough as Trails Off-Road Race Series, a set of single-track trail races held at multiple locations in North Carolina, including Eno River State Park, Uwharrie National Forest, and the Mountains-to-Sea Trail near Durham.

The series comprises three races on the following dates and locations: Eno River Run on 10/25/2026 in Durham. Uwharrie Mountain Run on 2/6/2027 in Uwharrie National Forest. Mountains-to-Sea Trail Challenge on 4/11/2027 near the Mountains-to-Sea Trail.

Each race offers multiple distance options:

• 6 miles
• 11 miles
• 8 miles
• 20 miles
• 40 miles
• 13 miles
• 50 km

Registration for the series opens on 7/15/2026 and closes on 10/24/2026. Series registration requires signing up for all three races; total cost depends on the distance chosen for each race. Participants must complete all three races in the series to be eligible for awards. Series scoring and awards are based on total mileage completed, with final distances calculated after the last race.

Distance changes must be requested at least one month before a race; approval is at the race director's discretion. No refunds or participant transfers are permitted after registering for the series. Adjusting to a reduced distance does not result in a refund and increasing distance may incur additional fees.

All series finishers receive a custom finisher award and the benefits and finisher prizes provided by each individual race. Visit the organization's website for the most recent information.
