C&O Canal 100
The C&O Canal 100 is a 100 mile race held on the C&O Canal each year during the final weekend in April. The event starts and finishes at Camp Manidokan near Knoxville, Maryland, and the course is described as almost entirely flat. The next scheduled running is April 24 and 25, 2027.
Aid stations are full service and, if cell service allows, electronic timing using Ultralive will be used at aid stations to provide live splits. Drop bags are permitted only at the Brunswick aid station and the Manidokan aid station. Brunswick drop bags must conform to Western States 100 dimensions 6" x 8" x 16" or be smaller; there is no size restriction for drop bags placed at Manidokan. The race includes a race shirt, a BOCO running hat, and a reusable cup with registration, and all finishers receive a belt buckle. Optional Patagonia jackets are available for purchase. A post race meal from Chipotle is included for runners at the finish and extra meal tickets are not available.
The 2026 edition is listed as a Western States qualifying race for finishers under the 30 hour cutoff. A volunteer credit system is in place so runners who spend 12 hours or more volunteering can earn credit toward the 2027 race. Registration for the 2027 race opens January 1, 2027.
