    GORE-TEX Kahtoola Uphill on February 21, 2026

    The GORE-TEX Kahtoola Uphill is a fun, family-friendly annual mountain race up and down the slopes of Arizona Snowbowl that celebrates human-powered movement.

    Choose Your Challenge

    Hike up using your preferred traction gear (MICROspikes® traction, hiking crampons, snowshoes, etc.), or skin up with AT skis or a splitboard (Midway and Öo’mawki only). With events ranging from easy to challenging, sign up for the Cambium Wealth Partners Fun Climb, Midway Climb or the Lumberyard Brewing Co. Öo’mawki Climb, or hang out at the base and cheer on the racers.

    • Cambium Fun Climb: A 1-mile journey with a 600 ft. elevation gain. Ideal for those seeking a short but rewarding climb.

    • Midway Climb – Traction: Tackle 3 miles and 1,550 ft. elevation gain using your preferred traction gear, perfect for a steady ascent and quick descent.

    • Midway Climb – Skinning: The same challenging distance and elevation, but for those preferring the ascent and descent with AT skis or a splitboard.

    • Lumberyard Öo’mawki Climb – Traction: Embark on a 3.5-mile race with 2,200 ft. climb, using your trusted traction gear for a more intense challenge.

    • Lumberyard Öo’mawki Climb – Skinning: For those who opt for skinning, this 3.5-mile race with a 2,200 ft. vertical ascent offers a unique mountain experience.

    • Note: Starting in 2025, the name of the Agassiz Climb has been changed to the Öo’mawki Climb (Hopi meaning "house of clouds"). The course will be the same, the only change is the name of that particular event. Thank you to the efforts from students in the Flagstaff High School Native American Club, who advocated to have the name of this peak restored.

    A Community Gathering

    • Free MICROspikes® demos: At check-in, Kahtoola offers a chance to demo MICROspikes® footwear traction. Availability is based on a first-come, first-served basis for racers and demos will be collected at the end of the race.

    • Costume/Dance Contest: Get creative and have fun! Whether you're racing or spectating, join in our costume/dance contest. It's a great way to add excitement to the day and show off your creative flair.

    We're headed to Buffalo Park to celebrate what will always be remembered as the three greatest decades of music...the 60's, the 70's, and the 80's. It won't matter if you love Sugar Sugar, No Sugar Tonight, or Pour Some Sugar on Me; you'll have a great time running & singing your way through the decades in Flagstaff.

    We've lined up some great race swag...Super race shirts and Finisher Awards! Add in age group awards for each race (including the half) in 5 year age groups, and you have the perfect event.
