Embark on an unforgettable trail adventure at the Friends of Yellow River State Forest Trail Run/Walk, a vibrant event kicking off on Friday, May 8, 2026, with races continuing into Saturday, May 9, in the stunning "driftless area" of Harpers Ferry, IA. Choose your challenge from a 21K, 10K, or 5K, and experience the breathtaking beauty of Yellow River State Forest, a region untouched by glaciers and boasting a unique topography of rugged bluffs, deep valleys, and meandering streams. This seventh annual event is more than just a race; it's a celebration of nature and community, where every stride supports the preservation of this cherished natural gem.

Prepare for a course that promises diverse and thrilling terrain through mixed hardwoods, tackling challenging uphill sections, rock outcrops, and steep slopes, balanced by smooth downhill glides. The extensive trail system offers panoramic views of Big Paint Creek and the surrounding valley, providing a scenic backdrop to your run. While some sections present an intermediate to difficult challenge with rocks, roots, and steep inclines, the trails cater to various skill levels. Aid stations will be strategically placed throughout the course to keep participants hydrated and energized. Typical race day conditions in early May feature comfortable highs around 68°F and lows around 46°F, with a low 18% chance of precipitation, creating ideal running weather.

What truly sets this race apart is its commitment to the Yellow River State Forest. As a 501(c)3 non-profit event, all funds raised are directly invested back into enhancing the forest for public use while protecting its ecological integrity. Participants can also opt for the "Dirty Double" to run both Friday and Saturday races and earn a coveted handcrafted ceramic mug. The Friday night 5K is a family-friendly event, even welcoming well-behaved leashed dogs, fostering a truly inclusive atmosphere. After conquering the trails, runners can enjoy post-race food, games, and giveaways, with prizes including canvas prints of the forest by local photographers.
