About the 15K Trail Race

Are you ready to take your trail running to the next level? Our 15k is designed to expose participants to the true essence of endurance trail running. The first 2/3 of the course will be our award-winning 10k...and then the FUN starts! The final 5k could be the one of the more challenging 5k's you've encountered. It starts by climbing the steep trail to RVR's famous triple zip line and then returning to the valley. The trail then enters the woods, winding through the pristine Prettyboy watershed directly adjacent to River Valley Ranch. Runners will follow a section from the abandoned Gunpowder Valley Railroad, built in the late 1800’s to service the Hoffman paper mills. It then returns to River Valley Ranch where you will climb to the highest point on RVR with a spectacular nearly 360 view of the Gunpowder Valley before returning to the finish area in the Old West town. Runners should be prepared to encounter rocky terrain, at least 5 SIGNIFICANT hills, several river crossings and occasional underbrush. While there will be 6 water stops, we still suggest runners bring their own hydration. IMPORTANT NOTE: Due to the challenging nature of this course we suggest your training plan be closer to a 1/2 marathon plan than a 15k. Also be sure to include regular hill training for best results.

About the 10K Trail Race

Our signature race, the 10k is an authentic Trail Run. If you are looking for a leisurely trail run like the NCR, this is not for you! This highly acclaimed course begins in the lush river valley and proceeds to the top of the Fort Roller hill, overlooking the scenic Western Town below. It then moves primarily through wooded trails (moderate to steep up and down grades) to a Rocky Ridge trail scramble where runners can choose from several paths that end in the same place. The trail then winds its way to the Cigar Tree Field where you’ll encounter a trail carved in one of RVR’s current crops, followed by the infamous "Dead Man's Hill" (relatively short but a doozy!). Gradually descending to the Gunpowder River, racers will next have the option to cross through the river (for the REAL trail runners of course) or across a single lane tree bridge. You'll then enjoy a flat series of single track trail following the river (a welcome cooler section of terrain), pass back thru the starting line, up Grave Run Rd, and back down thru our Old West town, across the covered bridge to the finish!'ve now completed one of America's Premier 10k Trail Runs!

About the 5K Road Race

This out and back course will begin in the woods of the lush valley of RVR on a groomed trail. It will then proceed for several miles on paved country roads lined with shade trees. The first 2/3 of the race is a slight incline while the second 1/3 is a slight decline. For those looking to PR on this course should be sure to plan for the slight elevation change (ie- be sure you leave something in the tank for the last 1/3 as you can fly through this section). The race will finish right through our authentic 19th century western town, crossing the Gunpowder Falls river through our covered bridge to the finish line. While not nationally ranked, our 5k course gets rave reviews from participants each year.
