River Valley Run Trail Half Marathon

Saturday, October 14, 2023 • Manchester, MD • Course Map

Set for its 8th annual running among the challenging hills and beautifully scenic valleys of the River Valley Ranch summer camp retreat just outside Manchester, a small rural town that lies less than an hour’s drive from Baltimore and Washington, D.C., the River Valley Run Trail Half Marathon offers gorgeous views and a course that organizers say will push every runner to her limit.

Run through the forests of northern Maryland. You’ll be running the race entirely within the grounds of River Valley Ranch, a summer youth camp whose history dates back to the early 1950s, when it was a summer cowboy camp for boys.

Today the camp now hosts more than 20,000 people annually for a series of summer camps for youth as well as retreats and outdoor education seminars for adults throughout the year.

Tromp through rivers (if you like). From the starting line at Fort Roller inside the camp, the race heads west toward the outer edges of the ranch, where you’ll have the opportunity to cross the river “wet or dry,” organizers say.

The course will feature plenty of rocky terrain as well as dirt surfaces on the trails through the woods, four “significant” hills and occasional underbrush as you run through the forest.

There will also be a few river crossings during the race, organizers say, and there will be 700 spots open for the half marathon — so all who are interested in running it are encouraged to sign up as early as possible.
