Prepare for an unforgettable challenge at the Pengelly Double Dip on June 7, 2026, in Missoula, MT. This iconic trail race, known for its demanding yet breathtaking courses, offers both a 13.1-mile half marathon and a formidable 10K. Runners will navigate the rugged and scenic terrains of Missoula's Mount Sentinel and University Mountain, tackling challenging ascents and descents amidst stunning mountain views and vibrant wildflowers. The Double Dip half marathon boasts an impressive 3,400 feet of elevation gain, taking participants over two summits, including the University Beacon. Meanwhile, the Bob Hayes Single Dip 10K is renowned for arguably the toughest first mile you'll ever encounter, featuring over 500 feet of elevation, which then rewards runners with the best views in town.

Starting and finishing at the Riverbowl East field near the University of Montana campus, the course weaves through the "M" trail, Crooked Trail, and Hellgate Canyon Trail, culminating on the Kim Williams Trail for the Double Dip. Typical race day conditions in early June include highs around 71°F and lows around 45°F, with only a 10% chance of precipitation, providing ideal weather for a mountain adventure. To keep runners fueled, the Double Dip features three well-stocked aid stations, and in the past, volunteers at the Beacon aid station have even dispensed margaritas. This is a cupless event, with participants receiving a HydraPak Speed Cup to fill at aid stations and the finish line.

The Pengelly Double Dip has a rich history, designed two decades ago to be an "epic" Missoula trail race. It honors local outdoorsman Dave Pengelly and is celebrated for its unique character, including a flying elephant mascot and post-race amenities like mimosas and pizza. Runners consistently praise the race for its brutal yet beautiful nature and the incredible vistas it offers. Whether you're conquering the "Double Dip" or tackling the "Single Dip," this Run Wild Missoula event promises a rewarding and memorable experience for those seeking a true mountain running test.
