Entry Fees


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 Active.com account until 4/16/2016.

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.

The race starts at Fort Roller and heads out towards the back section of River Valley Ranch. It then proceeds to work it's way down to the Gunpowder River where runners can choose wet or dry. The trail leads straight through RVR's old mine town Adventure Camp and into the pristine Prettyboy Watershed. Runners will follow a section from the abandoned Gunpowder Valley Railroad, built in the late 1800’s to service the Hoffman paper mills. After exiting the woods at Gunpowder Road (the site of the original Hoffman Mill), runners face a serious climb to the half marathons highest point. Moving back across Gunpowder Road, the trail will lead down to the Gunpowder River and through one of the gems of the Prettyboy Watershed: Hemlock Gorge. This section includes some small rock scrambles and single track that meanders through this gorgeous section of Carroll County. Runners should watch for exposed roots and rocks in this section but take moment to look up when it is safe so as not to miss some of the oldest and largest hemlock trees in Maryland. After exiting the gorge, runners will head back across Gunpowder Road and onto a long mostly wooded trail leading back to RVR. Once back at RVR the trail will head once more through Adventure Camp and follow the river to the final water crossing on the course. Switchbacks lead runners up the last climb, through Arrowhead Woods (RVR's Teepee Village) and to the FINISH in Fort Roller.
