Course Information
Race Course Summary
The Mesa Falls Marathon and Half Marathon races are point to point courses that begin in the Targhee National Forest near the headwaters of the Warm River and end in the city of Ashton, Idaho. Due to our geographic location and proximity to Yellowstone National Park, a wide variety of wildlife reside in the area including elk, deer, moose, bison, cougars, wolves, and bears. The race committee makes every attempt to clear the race course of unofficial entries prior to the race. However, recognizing that wildlife may not always follow our course rules, there may be four-legged “bandits” on the course at any point. Runners are reminded to use caution if and when encountering wild animals. Please give elk, deer, moose, and bison the right of way—they are bigger than you! If a bear or cougar are spotted, just remember that you don’t want to be the first runner—nor the last!

Course Map and Detailed Description
The Marathon starting line is located on Idaho Highway 47 the Mesa Falls Scenic Byway. Most of the course is on pavement. Vehicle traffic is generally light during the early morning hours, but will increase in numbers and speed as the day goes on.
