Discounts: Mainly Marathons participants can use the discount code in The Loony Bin newsletter and Mainly Marathons Facebook Group; and St. Cloud River Runners can use the discount code in the SCRR newsletter and SCRR Facebook group page. If you have any questions, contact us for details.
Food/Aid Stations: Due to our unique multi-loop course setup, we have one giant “aid station,” with more food and drink than you could ever need! Ask anyone who’s run at least one of our races; we’ve got everything from fruit to jelly beans to sandwiches, water to Gatorade to hot coffee, and everything in between. Way more than just granola bars and bananas–we even have our very own mobile kitchen, Loony Lunchbox!

Additional Details: These are not very technical trails, but there are “toe-catchers”, grass, gravel, and dirt. Also, if it rains, that means the trails will likely have wet + dirt = mud. As any good Boy Scout or Girl Scout knows, Be Prepared!
