PHASE ONE//ENDURANCE FEST

About the Event

Welcome to PHASE ONE//ENDURANCE FEST, an immersive endurance challenge set against the stunning backdrop of Spokane. This unique event draws inspiration from legendary races like THE LONGEST LIGHT and ZERO DARK ULTRA, inviting runners to push their limits through a grueling 24-hour format or tackle one of several distance options ranging from the kid-friendly SPRINT THE HILL to the formidable 101 Miler.
The race unfolds across diverse terrains in Spokane, including Reardan Cross Country track and scenic spots like Riverside State Park and Mt. Spokane State Park. Each lap measures 1.56 miles, offering runners a mix of challenges that test both physical endurance and mental fortitude. The event starts at 7 AM on June 19, 2027, with options to race day or night under the stars.
Support is key here; pacers are allowed for most events except for SURVIVE THE NIGHT, which tests runners' limits in a solo format from dusk till dawn. Aid stations provide essential Tailwind Nutrition and NeverSecond energy gels, along with water and snacks, ensuring participants stay fueled throughout their journey.
Participants will earn exclusive Phase One gear upon completion of various distances, including the coveted buckle for those who conquer 101 miles or 100 kilometers. The event also features a vibrant community atmosphere, enhanced by the Phase One Podcast where runners share stories of resilience and triumph.
PHASE ONE//ENDURANCE FEST is not just about running; it's an invitation to challenge yourself in breathtaking scenery while forging lasting connections with fellow endurance athletes.
