YMCA Sun Valley Half Marathon, 10K, 5K – JUNE 20, 2015

Be sure to mark your calendar with the new race date for 2015. June 20!

Experience one of the most scenic and traffic free courses imaginable. The Sun Valley Half Marathon, 10k, and 5K utilize our Valleys multi-user paved path system throughout the Cities of Sun Valley and Ketchum.

The courses start and finish in the Sun Valley Village on the spacious grass lawn in front of the Sun Valley Pavilion allowing for a relaxing spot for spectators to watch as family and friends cross the finish line. In addition, the Kids Fun Zone kicks off mid morning on the same lawn providing children’s activities and short distance races for the kids. All this happens while half marathon, 10k, and 5k racers complete their courses.



2015 registration will open December 1, 2014


Sun Valley Resort is once again offering special room rates for race participants. This is the ideal place to stay as the start / finish and post race activities are just a couple minutes walk from your room!

Join us for the fourth running of this soon to be fall classic. We have moved the race date a little closer to summer, tweaked the course a bit to create a solid challenge, and made it just a bit longer so all can enjoy the great mountain single track a little longer.

This run would not be possible with out the approval of our local US Forest Service office and the Sun Valley Resort.
