Tally in the Valley Trail Race 2026

The event takes place at Dundas Valley Conservation Area in Hamilton, Ontario. The race is sanctioned by Athletics Ontario. Race headquarters moved to the Trail Centre and the course will be run counter clockwise this year.

Participants run a 7 km loop through Carolinian forest on groomed double track with rolling hills and roughly 130 m of elevation gain per loop. The first 2 km follow a rail trail and are slightly downhill and exposed. The midsection includes runnable rolling hills and the most demanding 2 to 2.5 km of the loop returns runners to the Trail Centre.

Available distances and formats

  • 7 km one loop
  • 21 km three loops with a 4 hour cutoff
  • 100 miles 23 loops over 30 hours
  • 6 hour 12 hour and 24 hour timed events
  • Gong Show elimination with a 7 km loop every hour

Aid stations and services

There is an aid station at the start/finish offering water, an electrolyte drink, sweet and salty snacks, PB and J sandwiches, pickles and chips; menu items may change. Portable toilets will be available. A self serve water station is placed about halfway on the loop. Events are cup less so runners need a collapsible cup or bottle.

Additional notes

La Sportiva will bring a demo fleet of shoes and giveaways. THN Labs will supply gels in race kits and at aid stations; gels list four ingredients: maple syrup, tahini, sea salt, and rowanberry extract. Runners completing 23 loops (100 miles) receive a custom belt buckle; other finishers receive a custom medal. T shirt orders close July 1. Refund policy: a 100% race credit is issued for cancellations at least 30 days before the race; bib transfers are allowed. Visit the organization's website for the most recent information.
