River Valley Run Half Marathon Trail Race

  • River Valley Ranch 4443 Grave Run Road Manchester, MD, 21102 United States (map)

The River Valley Run Half Marathon Trail Race is now sold out.

We are excited to bring you our newest and most challenging race yet— our Half Marathon Trail Race! Continuing in our effort to provide Maryland’s Premier Trail run experiences, this half marathon is an endurance trail race that will push your limits! Running through the scenic Prettyboy Watershed along with the gorgeous hills and valleys of River Valley Ranch, it will be an incredible 13.1 miles!


Entry Fees

There are 500 spots for the Half Marathon. We encourage you to register online ahead of time, as we expect to fill to capacity. Prices will increase based on availability so register early to get the best price. Race Day registrants will pay $110 to run if spots are available (which we do not expect).

$90 - $110


The River Valley Run does not allow for refunds of entry fees. However, we understand that circumstances arise after you have registered so we do allow for transfers of registration so that a friend or family member may participate in your place, if you are unable to attend. You may transfer your registration to another person for a $10 fee. Available in your account until 4/14/2017.

As a certified Green Event, our goal is to have 100% non-paper registration; however, Packet-Pickup and Race Day registration will also be available, as space allows.
