Live results will only be available at Manidokan, Brunswick, and the North Turnaround.


The C&O Canal 100 mile race takes places on the scenic C&O Canal each year during the final weekend in April. The race starts and finishes at Camp Manidokan near Knoxville, Maryland.

The C&O Canal 100 course is almost entirely flat and offers plenty of opportunities for success both with new 100 mile runners and old veterans who are up for a challenge on a beautiful course.

The 2024 date will be April 27 -28, 2024. Registration opens on January 1st, 2024 at 10AM EST.

To make the 2024 race a success we will need to find plenty of volunteers! To encourage runners to sign up we have a policy where volunteers can earn credit for the 2025 race. Runners who spend 12 hours or more volunteering at the race will be eligible for the credit. You can find details of that system hereA link to sign up as a volunteer is currently open on Ultrasignup. Volunteers from the 2023 race can complete the form found here to apply for credit for the 2024 race.

2024 Race Details

Race swag: A C&O Canal 100 race singlet and a BOCO running hat is included with registration and all finishers will receive a belt buckle.

Post-race meal: A post-race meal from Chipoltle is included with registration and will be available at the finish for all runners. It is not possible to purchase extra meal tickets for friends/family.

Electronic timing: We will be using electronic timing at all aid stations which will simplify the timing process giving you better access to your live splits. Your friends and family will be able to track your progress during the race and know where you are on the course if cellular coverage allows.

Aid stations: Dargan Bend AS will have limited aid. All other aid stations will be full service. For more details on what you can find at the aid stations please see the aid station page.

Drop bag: Drop bags will be permitted at Brunswick AS, and Manidokan AS. 

We will still be enforcing the strict drop-bag size limits. Brunswick drop bags will need to follow WS100 dimensions (6″x8″x16″) or be smaller. If your drop bag is larger, we won't accept it. We simply do not have enough room to transport huge drop bags or store them at the aid stations. There are no size restrictions for drop bags placed at Manidokan AS. Victory Sportsdesign has generously offered a 10% off discount to buy their drop bags for all entrants, or you can make your own drop bag that conforms to the dimensions.
