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.

2015 Event

The 2015 was on April 25-26.


  • The course will remain unchanged from last year (2014).
  • We will again be holding a pre-race dinner, but to have a better idea of hoe many people to expect you will be asked to pay at registration rather than at the door..
  • Race premiums in the form of Patagonia jackets will make a return this year, however this will be the last year we will offer Patagonia jackets. The price has increased since last year to account for increased in the printing of the race logo on the jacket.
