Hagg Lake Triathlon and Trail Festival

Embark on an unforgettable trail running adventure at the Hagg Lake Triathlon and Trail Festival, set for June 21, 2026, in the stunning natural beauty of Gaston, Oregon. As one of the nation's oldest and most scenic multi-sport events, this festival offers a vibrant atmosphere and challenging courses for both seasoned trail runners and those new to the dirt. With typical race day conditions boasting highs around 75°F and lows around 50°F, alongside a mere 4% chance of precipitation, runners can expect ideal weather to conquer the picturesque routes.

The Half Marathon (13.1M) trail run presents a challenging and fun clockwise loop around Hagg Lake, demanding runners to navigate steep climbs, descents, tree roots, branches, dirt, mud, and rocks. While some sections may require walking, the course is renowned for its epic scenery, offering breathtaking views that make every effort worthwhile. For those seeking a shorter but equally engaging experience, the 5K trail run provides a scenic out-and-back course along the lake, featuring gentle hills and the same natural beauty. Aid stations on the half marathon course offer water, electrolytes, and snacks, though runners are encouraged to carry personal hydration given the course's challenging nature and potential gaps between stations. Both races start and finish at Bobcat Cove, providing easy access for spectators to cheer on participants amidst a festive environment.

Beyond the individual races, the Hagg Lake Triathlon and Trail Festival is celebrated for its rich history, exceptional venue, and welcoming camaraderie. Runners consistently praise the well-marked courses and seamless logistics, ensuring a smooth race day experience. Many participants enjoy the option of tent camping on-site, fostering a unique community spirit where stories are shared and new friendships forged. This isn't just a race; it's a historical event and a true celebration of endurance sports in one of the Pacific Northwest's most gorgeous settings.
