21K de Montréal : Half marathon details
The event is a 21.1 km half marathon on the Circuit Gilles-Villeneuve at Parc Jean-Drapeau, scheduled for 18 April 2027. The course has a certified OR measurement with oversight from Athlétisme Québec and includes an elevation change of +34 m and -26 m. A time limit of 3 hours applies. The maximum field is 5 000 runners and the recommended minimum age is 18.
The route contains a gravel segment of about 1.1 km that is run twice, between km 0.7 and 1.8 and again between km 17.4 and 18.5. Aid stations on course and at the finish provide water and electrolytes, and toilets are available near some stations. Timing mats on the course record intermediate times and the chip time is used for public rankings; prize money is reserved for athletes in the Elite wave.
Race services include pacers, a baggage check on site with retrieval by coupon, a finisher medal, and a post-race snack. The official event shirt is not included automatically and can be added separately during registration.
Bib pickup is handled at designated collection points in the days before the race. It is not possible to pick up a bib on race day. A photo ID and the confirmation QR code are required; a third party may collect a bib with a signed authorization and copies of both IDs.
Tracking of participants is available through the event mobile application. Visit the organization's website for the most recent information.
