American Birkebeiner

"The American Birkebeiner—known simply as the Birkie—is North America’s largest cross-country ski race and a cornerstone of endurance sport in the U.S. Held each February in Wisconsin’s Northwoods, Birkie Week features a full slate of races, including the 50 km skate and 55 km classic races, the 29 km Kortelopet, and the 15 km Prince Haakon. Participants traverse the rugged, snow-covered Birkie Trail, climb through rolling hardwood forests, cross frozen Lake Hayward, and surge over the towering International Bridge to a dramatic finish on Hayward’s snow-lined Main Street.

More than 10,000 skiers from around the world take part, cheered on by 20,000 spectators lining the course and streets. The Birkie draws Olympians, World Cup veterans, and weekend warriors alike, with start waves organized by experience and pace. For a more relaxed experience, the Open Track events earlier in the week provide access to the same course with fewer crowds. Despite variable snow years, organizers maintain the event’s legendary atmosphere through course modifications, snowmaking, and community support. Steep climbs, energetic fans, and a deep-rooted legacy dating back to 1973 make the Birkie a pinnacle challenge on the global ski calendar."
