The race will tentatively end around 10pm with the last few runners picking up the pace every mile to beat the clock that is diminishing with ever lap! The cutoff for each lap will be one minute less than the previous lap. We will start the race at 6:30am and give runners 45 minutes to complete the 2 mile loop. Runners completing the laps early must wait for the clock to start the next scheduled lap. If you fail to complete the 2 mile loop in the required time please ring the cowbell and turn in you race bib. On the 31st lap (if we get there) the first runner to complete the lap will be the winner. 
This style of event welcomes all paces and levels of runners. If you are looking to knock out your first 50k this event is for you! If you are looking to challenge your furthest distance with 50 miles step right up! And if you are looking to compete and take your challenge to the next level look no further! The course will be trail, rolling, partly shaded! Bring your 10 x 10 pop up, a lawn chair, and lets make it a party.

Course Map - HERE

This event is held at a nature preserve with an old barn that has been repurposed as an educational center of sustainability and renewable energy. The 2 mile course is held on a grass path that is very wide and includes a few rolling hills. During the route keep your eyes up looking for deer, birds, and a few foxes meandering through the woods.

We will have a basic aid station at the start/finish line of this 2 mile loop race format. Items may include: pickles, cookies, chips, Little Debbie snacks, assorted candy, chicken/veggie broth, fig newtons, & pretzels. Liquids will include water, Tailwind Nutrition, coke, and ginger ale.

Personal Tent Set Up & Drop Bags

Athletes are permitted to have a drop bag or personal tent near the aid station in the open field adjacent to the start/finish line loop outside of fireside hall. Even if it rains. Please be mindful to place your personal belongings off the course as to not impede the runners, the flow of traffic, or other race participants. The start and finish line loop will serve as the official drop bag area designation.
