USO Denver

USO Denver is a private 501(c)3 nonprofit organization that strengthens America’s military service members by keeping them connected to family, home and country, throughout their service to the nation. By running Colfax for the USO, you’ll become part of The Force Behind the Forces in the Denver Metro Area. Please consider USO Denver as your race charity of choice and support currently serving military members and their families of all five branches, who are active duty, national guard or reservists!  For more about joining Team USO for the Colfax Marathon, including benefits, visit or contact Gayle Melges at
