Dewey Beach 100 Miler

The Dewey Beach 100 Miler & 24-Hour Run is an intimate ultrarunning event held in Dewey Beach, Delaware. Featuring a simple yet challenging 1-mile out-and-back road loop starting at Dewey Beer Co., runners repeat the loop to reach 100 miles or run for 24 hours. The course is flat with no elevation gain, ideal for testing endurance and mental toughness.

This grassroots race is fully self-supported, with no aid stations or pacers, encouraging runners to rely on their own gear and grit. Limited to 23 participants, the event offers a raw, community-driven atmosphere alongside ultrarunning legend Mike Wardian. Visit the organization's website for the most recent information.
