Races in May 2027 — FAQ

How many races are there in May 2027 in Canada?
39 with a confirmed date, and the biggest group is 5K races with 30. The busiest single day is Sunday, May 2, 2027, with 7 races. Recompiled nightly from the organizers' own calendars, so the number moves as races are announced.
When should I register for a May race?
Most Canadian races take entries until race week — what expires first is the price tier, not the spot. Check the fee window on the race's page before you wait.
