Prepare for an unforgettable winter challenge at the Snow Joke Half Marathon, an iconic Western Montana tradition held on February 28, 2026, in scenic Seeley Lake. This 13.1-mile race invites runners to embrace the elements on a unique course winding through the heart of the Seeley-Swan Valley, nestled amidst the Bob Marshall and Mission Mountain Wilderness Areas. You'll navigate a single loop around Seeley Lake on snow-plowed roads, encountering gently rolling hills and approximately 146 meters of elevation gain. Expect stunning scenery, with pines and mountain views accompanying you along the route, though organizers advise preparedness for potential icy patches and snow-packed sections on the back roads.

The Snow Joke Half Marathon is renowned as one of the country's coldest outdoor race events, offering a rustic, no-frills experience where grit and good spirits often take precedence over personal records. Typical race day conditions in late February see highs around 36F and lows near 18F, with an 11% chance of precipitation, but be ready for temperatures that can shift from bright winter sun to heavy snowfall. Beginning at the unusually late hour of 11:00 AM from Seeley Lake Elementary School, this race, now in its 47th edition, welcomes leashed dogs, even offering a soup bone prize for the first canine finisher.

Run Wild Missoula orchestrates this community-focused event, which has grown from a small gathering of 30 runners in 1980 to attracting upwards of 700-900 participants today. Aid stations provide hydration, but this is a cupless event, so runners should bring their own devices, and water and treats are available for your four-legged running companions. All finishers are celebrated with a custom medal, and post-race festivities include delicious pancakes and a complimentary beer for those 21 and over.
