Race Info

The Armed Services Marathon, Half Marathon & 5K honors all branches of our military as well as our first responders. Each branch will have a booth and/or exhibit in the stadium. We will have a Joint Services Honor Guard presentation before the singing of the National Anthem. Each military branch will staff an aid station for your support and our participants will vote which aid station they enjoyed the most. The winning branch will be awarded the “Traveling Trophy.” Our four time defending champions, the U.S. Marine Corps proudly display it in their office. Source
