Travel: Rapid City, SD is the closest airport. All driving distances between races are under 200 miles per day.
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 Goo and bananas (although the banana smoothies really hit the spot on hot days)!
