The Lost Valley Trail Race 2025

The Lost Valley Trail Race is a new point-to-point trail running event debuting in 2025 along the scenic Iroquoia Section of the Bruce Trail. Runners can choose between 10 km and 25 km distances, both finishing at the beautiful Dundas Valley Conservation Area. This event fosters a close-knit community atmosphere with limited registration to just 150 participants, offering a grassroots vibe that emphasizes camaraderie and connection with nature.

​

Both courses feature a net downhill profile with varying elevation gains and losses, marked carefully with the Bruce Trail's white blazes and additional course markings in key areas. Participants should bring their own collapsible cup or bottle as the race is cup-less, and shuttle service from the finish line to the start is provided to ease race-day logistics.
