The Beav Trail Race is an annual trail running event held at Hilton Falls Conservation Area in Milton, Ontario, known for its exceptional groomed trails and technical sections. It offers multiple distances including 10km, 25km, and 50km races across scenic routes featuring the Bruce Trail, a waterfall pin collection, and challenging single and double track sections.
