The Lost Valley Trail Race 2026
The Lost Valley Trail Race takes place on October 24, 2026 and finishes at the Dundas Valley Conservation Area, Governors Road, Dundas, ON. It is a point-to-point trail event on the Iroquoia Section of the Bruce Trail, running from Burlington to Dundas. Both courses use the Main Trail, which is permanently marked with white blazes; participants must be able to follow trail blazes. Only the first 250 m, last 250 m, and the 2.5 km road section in Dundas will have additional markings.
Distances:
- 10 km start at Rock Chapel Conservation Area, finish at Stacey Meadow Pavilion.
- 25 km start at Cityview Park in Burlington, finish at Stacey Meadow Pavilion.
The 25 km route has about 600 m elevation gain and 720 m elevation loss and is net downhill. The 10 km course is roughly 75% trail and 25% road, with about 185 m gain and 265 m loss. Aid stations: three on the 25 km course (7.5 km, 15 km, 20 km) and one on the 10 km course (around 5 km). The event is cup-less; participants need a collapsible cup or bottle. A bus returns participants from the finish to the start locations and parking at Dundas Valley Conservation Area is included in registration. Registration is limited to 180 participants in 2026. Ten dollars from each registration is donated to the Iroquoia Bruce Trail Club. Visit the organization's website for the most recent information.
