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 2020 event will be held on April 25-26, 2020.

The 2020 Race Details

Race swag: C&O Canal 100 Patagonia Race Singlet (included with registration).

Post-race party: A post-race meal is included with registration (11am-1pm+ Sunday) and we encourage everyone who finishes earlier to shower/rest and come back to celebrate/socialize with all of your fellow runners and cheer on the final finishers!

Buckle ceremony: Belt buckles will be awarded after the final finisher during the post-race party. Each finisher will have their name with finishing time read and then receive their buckle.

Fully electronic timing: We will be using electronic timing at all aid stations which will simplify the timing process and give you better access to your splits. Live results will be published as cell service allows.

Drop bag - A new drop bag location has been added for the 2020 race (Dargan Bend AS). 

We will still be enforcing the strict drop-bag size limits. Dargan Bend AS and Brunswick AS drop bags in 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.
