The Lost Valley Trail Race
The Lost Valley Trail Race 2026 : description
The Lost Valley Trail Race 2026 finishes at Dundas Valley Conservation Area and runs along the Iroquoia Section of the Bruce Trail between Burlington and Dundas. The event is sanctioned by Athletics Ontario and offers two distances.
- 10 km
- 25 km
Both courses are point to point, with the finish at Dundas Valley Conservation Area. Participants may board a bus provided from the finish to the start, or arrange their own drop-off. Parking at the finish is included in the registration fee. Both routes follow the Main Trail white blazes; additional markings appear in the first 250 m, the last 250 m, and on a 2.5 km road section.
The 25 km course lists roughly 600 m of elevation gain and 720 m of elevation loss, with three aid stations at about 7.5 km, 15 km, and 20 km. The 10 km course is about 75% trail and 25% road, with roughly 185 m gain and 265 m loss, and one aid station near 5 km. Aid stations provide sweet and salty snacks, water, electrolyte drink, PB and J, and similar items. The event is cup-less; participants must bring a collapsible cup or bottle. Poles are permitted.
Race inclusion items note the bus ride to the start, Happy Trails Racing socks, a neck gator, sticker, a small custom bib, a finisher medal, and parking. Ten dollars from each registration goes to the Iroquoia Bruce Trail Club. Registration is limited to 180 participants. La Sportiva will attend with demo shoes and giveaways, and THN Labs supplies gels in race kits and at aid stations. Visit the organization's website for the most recent information.
