Course Description

Half Marathon Trail Course Description:

Are you ready to take your trail running to the next level? Keeping with what makes our 10K one of the best races in America, we have designed our Half Marathon to expose participants to the true essence of endurance trail running. 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 beautiful Prettyboy Watershed. After exiting the Prettyboy section, 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. The final trail leads runners up the last climb, through Arrowhead Woods (RVR's Teepee Village) and to the FINISH in Fort Roller.

NOTE: Due to recent restrictions placed on us by the Baltimore City Department of Public Works (who oversees the Prettyboy Watershed) we've made some changes to the Prettyboy watershed section and developed new trail sections on the RVR property which will feature some exciting single track sections to complement the wider Prettyboy trails.
