This is the fourth year for our most challenging trail run yet— our Half Marathon Trail Run!

Much like our August Trail Run Festival, we're pulling out all the stops to provide you with a premier Maryland Half Marathon Trail Run experience. Our goal is for this to be one of the best half marathons in Maryland and beyond, giving you an extreme running challenge and endurance trail run that will push your limits! Running through RVR's scenic, wooded property with the gorgeous hills, valleys, and river will be an epic 13.1 miles to remember!


Entry Fees


Cancellation/Transfer Policy

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 4/19/19.

Deferment Policy

In addition, you may defer your 2019 registration (for medical reasons only) to the 2020 event for a $10 fee. Deferments are for one year's use only and cannot be applied to subsequent years after that time. To defer, fill out and submit the form below. The deadline for deferment is April 19, 2019.
