Aspen Backcountry Marathon

Aspen Backcountry Marathon Info

New Route & New Half Marathon.

Utilizing the amazing trails that surround Aspen, this full marathon is run almost exclusively on dirt trails. The diversity and elevation gain will challenge even the well trained athlete. The race will be open to individuals and relay teams. While the route has spectacular views of the Elk Mountain range and the city of Aspen below the ascents and descents will keep everyone challenged. There is over 4100 feet of vertical for the marathon and 2500 feet of vertical gain for the 1/2 marathon.

New this year there will be a 21K aka a half-marathon!  All races will start and finish at Rio Grande Park. By finishing in Rio Grande Park during the Aspen Ducky Derby, participants will be greeted by a crowd of spectators and supporters.


  • There will be a cash purse of $2400 for the Marathon
  • King of the Mountain: you must finish the marathon to be eligible to win the KOM! And more prizes - check out the website
