Demi Marathon Lachine
The event takes place along the shore of the Lachine Canal on a loop course that starts at Boulevard St‑Joseph and returns along the bike path passing Parc Noël‑Spinelli, Parc Saint‑Louis, Parc Fort‑Rolland, Stoney Point and Summerlea. The start and finish are adjacent, with access to a sponsor zone where music, a children’s inflatable, tastings and exhibitor tents are scheduled for the 2025 edition.
Participant numbers are limited. For 2025 the registration opens on February 15, 2025 and is scheduled to close in September 2025 (date indicative and may close earlier). The deadline for registration changes is October 4, 2025 at 15:00.
Registration includes an official t‑shirt, a participation medal for finishers, a post‑race snack and refreshment, access to the sponsor zone and a downloadable runner passport. Awards are given to the top three men, top three women and top three non‑binary finishers in each category; youth awards are planned for 13 and under in the 1 km and 2 km events.
Technical and policy details: course measurement is certified by Athletics Canada (2024 certifications for 5K, 10K and 21.0975K). Water stations follow Athletics Quebec criteria (first at 3 km, then one every 5 km and one at the finish, six stations total). Registrations are non‑refundable; an optional registration refund service is available for a fee and covers certain personal reasons but not event cancellation. Fees apply for distance changes, participant transfers and deferrals; bib resale is prohibited and leads to disqualification. The half marathon requires participants to be 18 or older and has a 3 hour time limit. Strollers are permitted only on the 10 km, 5 km, 2 km and 1 km distances.
