About
C&O Canal 100 is held in Brunswick, Maryland, on April 24, 2027. There is one format: 100 miles (160.9 km) along the C&O Canal, with the start at 7:00 AM.
A hundred miles on canal terrain is a very different proposition from a mountain ultra. There is little climbing to break the rhythm, so the same muscles work the same way hour after hour and pacing discipline decides your day — most finishers walk planned segments from early on rather than waiting until they have to. Build with long back-to-back weekends, test your shoes and nutrition over at least one 50-mile effort, and plan for running through the night with a crew or a drop-bag system you have used before.
