Aspen Backcountry Marathon Safety Plan. This race will be a limited support race. There will be food and water stations, volunteer crews with EMT and First Responder experience. Please do not expect a high level of runner support like other marathons can offer. The logistics of a backcountry race makes additional support very difficult. In addition, we have to be careful about impacting the environment since it is at a high altitude, remote, and on National Forest Service land.
