Teton Dam Marathon, Half Marathon, 10K & 5K

Saturday, June 1, 2019 • Rexburg, ID • Course Map

An out-and-back race that takes runners on a commemorative tour of the site of the famous Teton Dam break, which inundated the nearby town of Rexburg in 1976, the Teton Dam Marathon, Half Marathon and Relay offers views of beautiful scenery, quaint towns and farmland and wide expanses of open spaces.


Runners start the USATF-certified course next to Madison Jr High School in Rexburg. From there, the race follows a route through the rural areas just outside Rexburg, with several uphill segments in the first few miles of the race.

That changes once runners are approaching the half-way point of the race, where the course begins to rise around the mile 5 marker, climbing more than 300 feet over the next couple of miles.

You’ll make your way across the Teton River twice during the half marathon, first  between mile markers 3 and 4, and then again a second time around the mile 8 marker.

Race organizers encourage runners planning on this race to include hill training in their preparations, as the course’s gentle, rolling hills meet runners all throughout the race. The event usually host a small field of runners, which past participants say adds to its personal, intimate charm.
