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!
What about the bling?
All participants, regardless of distance, receive a shirt, a Starter Medal (traditional medal with ribbon), a Year Tab Medal (year of completion), and a State Medal (in the shape of the state and details specific to the state) for each state/race they complete in the series. A bonus Series Finisher Medal is earned by those completing all days/states in a series. All of the medals then connect to make a string of bling!
We even give a special award to each person participating in his or her first full or half marathon!
The best part, the caboose medal, which is earned by the final finisher of each marathon and half marathon!
Registration information is below. You may do any number of races; special medals are awarded to those who complete all six!
