Storm the Woods - Mason Run at Chester Woods 2026

Join us at Chester Woods Park in Eyota, MN for a trail adventure like no other. Part of The Storm Trail Race Series, this event carries on the legacy of the Mason Run with new energy and community impact.

This year marks the 20th Annual Mason Run, and we’re celebrating in a big way—by adding a brand-new 20 Mile race to the lineup! It’s the perfect distance to honor two decades of trail tradition while testing your endurance on Chester Woods’ rolling terrain.

Choose your challenge—5K, 10 Mile, 20 Mile or 50K —on scenic trails featuring rolling terrain, wooded paths, and the notorious Big Dam Hill. Expect well-stocked aid stations, great swag, and a finish-line celebration that feels more like trailgating than a race.

Come storm the woods and be part of something bigger—your run supports youth mental health programs through Storm Sporting Events.
