About the Event

Test your endurance against the clock on a fast, scenic loop at the Pulse Endurance Runs at Eagle Island State Park from March 19-21, 2026. Idaho's premier timed event offers a flexible challenge for every level, with options ranging from a 6-hour night run to a monumental 48-hour ultra, plus a dedicated 100-mile fixed-distance race and a fun team relay. The flat 2.5-mile dirt trail loops along the Boise River and Eagle Island pond, providing a perfect setting for personal records, first ultras, or nutritional testing in a supportive, community-focused atmosphere.

Experience a meticulously organized multi-day festival where the goal is to run as many miles as you can within your chosen timeframe, with no traditional DNFs except in the 100-mile race. With a fully stocked aid station every loop, ample crew access, warming tents, and vibrant energy from fellow runners, it's an ideal environment to push your limits. Whether you're a seasoned ultrarunner or seeking a new adventure, the Pulse Endurance Runs provide a unique and accessible stage for achievement just outside Boise.
