About the race
Big Wolf’s Backyard Ultra – Cacouna is a last-one-standing backyard ultra held on June 27th 2026 on a repeating loop of 6.706 km with 52 m of positive elevation. The format uses the same loop repeatedly, day and night, and participants run successive laps until only one remains.
The loop runs on gravel and crosses varied terrain including fields, a marsh, a wooded area and a river. Participants start from the heliport runway and the site offers a wide rolling course with views of the St. Lawrence River. The location sits between the municipalities of Cacouna and L’Isle-Verte at Quai de Cacouna Est.
Runners are fully responsible for their own food and drinks; only water is provided on site. Athletes may set up in the large common tent with their chair, bag and cooler. Required equipment listed for entrants includes a chair, a survival blanket (160 cm x 200 cm), at least eight litres of food and hydration at the start, a headlamp with a spare battery (minimum 150 lumens), one standard box and a small cooler per runner, and a waterproof raincoat.
Each runner may be accompanied by one support person who must be identified by a badge while on site. The site can hold heat in summer and may bring humidity and cool nights, while a river breeze often reduces mosquito activity. Visit the organization's website for the most recent information.
