Granite Gorge Yo-Yo Run.

Lace up for an unparalleled mountain running experience at the Granite Gorge Yo-Yo Run, set to challenge runners on Sunday, October 25, 2026, in scenic Keene, NH. This 4.9-mile race is far from a typical trot, promising an exhilarating test of endurance as participants tackle the "Yo-Yo" course—ascending and descending the mountain four times. Runners will navigate mostly ski trails with some single-track sections, accumulating an impressive 1,650 feet of elevation gain over the short but intense distance.

What makes this event truly unique is its relentless up-and-down profile, offering a thrilling challenge in a beautiful outdoor setting that's unlike any other mountain race. Typical race day conditions in late October often see comfortable highs around 56F and lows around 34F, with a modest 15% chance of precipitation, creating crisp, invigorating running weather. Beyond the personal challenge, the Granite Gorge Yo-Yo Run fosters a strong sense of community spirit, benefiting the Keene Community Kitchen and encouraging participants to bring food donations. Top male and female finishers can vie for prize money, while unique age group awards and raffle prizes add to the festive atmosphere at Granite Gorge Mountain Park.
