 The Army Ten Miler, the second largest 10 mile race in the U.S., is a massive, historical running event throughout Arlington, VA and Washington, DC. This year will mark the 35th Annual race, as it was cancelled in 2001 during the aftermath of the 9/11 terriost attacks. 

This year, COSF is proud to be represented by 25 athletes on this race of a lifetime! The only thing better than completing a tough physical feat, is completing a tough physical feat while helping others! Our team is comprised of COSF staff, board members, donors, service members, veterans and college students!
