The Falling Water Trail Marathon and Half Marathon is a premier trail running event held annually in Eugenia, Ontario, organized by Happy Trails Racing. The 2026 edition is scheduled for August 8 and 9, drawing trail runners from across the region to experience the rugged beauty of the Beaver Valley section of the Bruce Trail. This event is renowned for its challenging terrain, technical trails, and breathtaking scenery, making it a favorite among experienced trail runners seeking a true test of endurance and skill.

Sanctioned by Athletics Ontario, the event upholds high standards of organization and safety. Participants can choose between the marathon, half marathon, or the unique "Bruce Deuce" challenge, which involves running both distances over the weekend. The race is also known for its strong community atmosphere, partnerships with brands like La Sportiva, and opportunities for runners to demo trail shoes and win prizes. Whether you're aiming for a personal best or simply want to immerse yourself in Ontario's natural beauty, the Falling Water Trail Marathon and Half Marathon offers a memorable and rewarding experience.

The course traverses the Beaver Valley section of the Bruce Trail, renowned for its technical, single-track terrain. Runners will encounter rocky and root-filled paths, steep ascents and descents, and several sections with exposed tree roots and uneven footing. The marathon and half marathon routes both feature significant elevation gain, with the marathon offering a particularly demanding profile. The trail is almost entirely off-road, winding through forests, along escarpments, and past waterfalls, providing both physical and visual challenges. Participants should be prepared for variable trail conditions and bring appropriate trail running gear.
