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 2019 Race Details

Here is a summary of some previous changes which remain in effect:

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

Post-race party: The post-race meal will now be 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 now 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 this year at most aid stations which will simplify the timing process and give you better access to your splits. Live results will be published from all aid stations except the north turnaround and Dargan Bend.

Drop bag - We will still be enforcing the strict drop-bag policy in 2019. Manidokan and Nolands Ferry AS drop bags in 2019 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. Victory Sportsdesign has generously offered a 10% off discount to buy their drop bags for all entrants, or you can make your own that conforms to the dimensions.
