GAP/C&O has become one of the premiere bike touring destinations in America; the GAP estimates over 1M annual visitors, and over 100K through riders, while the C&O Canal Towpath estimates 5M annual visitors, putting it in the top 10 among national parks. A bunch of friends have done or are planning to do it, and it’s easy to see why; it’s 95% off road, 90% on gravel, all rail-trail or canal path, so it’s pretty much all low-stress and easy riding.
Climate Ride’s plan had us doing the 340 miles in 5 days, which is more daily mileage than I’d usually plan, but it is pretty easy to make time when there are no intersections. We’d do two days of very gradual climbing up a rail grade to the eastern continental divide, then three days of very gradual descending on the tow path into Georgetown. Totally Doable!
