The Reaper is a 14 hour overnight trail running event on Halloween Weekend. You can race as a solo runner or a team of 2, 4 and 6 runners. The goal of this event is to earn points by completing loops on the course and winning games in the Reaper Village. There are 3 different courses to choose from, each varying in length
(1.2 miles - 5.1 miles), difficulty and point value. We also throw in a joker lane that is open only for a few hours during the race but gives you the opportunity to earn some serious points. When you hear the joker over the PA, it's game on and the joker lane is open. Your team can also earn points Inside the Reaper Village by placing top 3 in one of our many games being played. Using a knock out tournament format, we have 3 legged races, sack races, hot potato, beer chug, bags tournament, flip cup, runway costume contest, karaoke contest and other carnival type games throughout the Village. 

Along with running and games, you'll find live music, a bonfire, food trucks, local craft beer and official Reaper merchandise inside the Village. Each team is given an area inside the village to setup a 10x10 or 10x20 tent / pit area. This is where you'll keep all your gear for the night, catch some sleep and just hangout with your buddies. Make sure you bring some battery powered lights to illuminate and decorate your tent area. We're in the woods, it gets dark! The Village is completely lit up all night long and the courses are heavily marked with glowing markers and extra lights in the more technical areas of the course. 

The Reaper is unlike any other race out there. Strategy plays a massive role in the outcome of this event. Points are updated every 3 hours during the race. It's all about having fun in the woods with like minded people. The race is laid back, very organized, and tons of fun. Get creative, bring your buddies and prepare for a unique and fun overnight trail running experience with your best running buddies.
