About the race
The Lost Valley Trail Race 2026 is a point-to-point trail running event on the Iroquoia Section of the Bruce Trail, finishing at the Dundas Valley Conservation Area in Dundas, Ontario. The event offers two distances:
- 10 km
- 25 km
Both distances are point-to-point with different start and finish locations. Participants are transported from the finish area to their respective start lines by bus, and parking at the Dundas Valley Conservation Area is included in the race fee for participants. The Main Trail of the Bruce Trail is marked with white blazes; additional course flags appear only for the first 250 m, the last 250 m, and a 2.5 km road section through Dundas.
The 25 km course starts at Cityview Park in Burlington, follows single-track along the Niagara Escarpment and Smokey Hollow, includes rocky sections, a tunnel under Hwy 6, and descends to Dundas. Total elevation is about 600 m gain and 720 m loss. The 10 km course starts near Rock Chapel Conservation Area, is roughly 75% trail and 25% road, and has about 185 m gain and 265 m loss; the largest descent is on a technical section where runners should descend slowly.
There are three aid stations on the 25 km course (7.5 km, 15 km, 20 km) and one near 5 km on the 10 km. Aid station supplies include sweet and salty snacks, water, electrolyte drink, and PB and J. The event is cup-less; participants must bring a collapsible cup or bottle. Poles are permitted. Race kits include a bus ride to the start, socks, neck gator, sticker, custom bib, aid stations, finisher medal, and a donation to the Iroquoia Bruce Trail Club. Registration is limited to 180 participants in 2026. The event is sanctioned by Athletics Ontario. Visit the organization's website for the most recent information.
