The Delmarva Ultra Challenge (DUC)

The Delmarva Ultra Challenge (DUC) - 100k Trail Race

The Delmarva Ultra Challenge (DUC) 100k trail race was created to give Algonquin fans something different. This race is designed for those who value a good old fashion challenge, being outside their comfort zone, or not shying away from a high risk, high reward scenario.

The race format consists of running two 50K trail runs back to back. The first 50K is on Friday night after packet pickup at an undisclosed location, revealed only a few hours before the start. The second 50K is the traditional Algonquin race course the following Saturday morning. The runners' two times will be added together to determine the top male and female DUCs.

Qualification: If you signed up to run the Algonquin and have completed a 50-mile race or longer within the last year, finishing under the official cut-off time, you are qualified for consideration. There are 30 open spots, with the final decision made by the Race Dictator and General Gabe.

Keys to success: Night experience running, a high tolerance for pain, and a strong mind are all essential for crossing the finish line and earning the right to be called a DUC!
