Spring races in Canada (2027)
113 races have a confirmed date between March 1 and May 31, 2027 — 19 in March, 20 in April, 74 in May — and another 266 ran last spring and have not announced their 2027 date yet, so 70% of the spring races on this page are still waiting on one. It fills in through the winter as organizers publish, and is rebuilt nightly. March is shared with the winter racing guide, which runs to the end of the month.
Two kinds of listing on this page. Every date shown is one an organizer has published. The second list is different: those races ran last spring and have not yet said when they run in 2027, so they are filed under the month they usually run, with no date attached. A guessed date shown as a real one would be worse than no date at all.

Spring by the numbers
Across all 379 races on the spring calendar, confirmed or usual, 67% include a 5K, 48% a 10K and 21% a half marathon or longer; 21 include a full marathon. Ontario holds 29% of them.
What spring weather actually does
Ten-year weather normals for the week and town of 370 of the 379 spring races; the rest are in places without a weather record. Across every race town with a weather record, the typical daily high climbs from 0°C in the first week of March to 20°C by the end of May — a 20° swing inside one season, which is why a March race and a May race call for different kit.
| Month | Typical high | Typical low | Days wet | Races measured |
|---|---|---|---|---|
| March | 7°C | -2°C | 43% | 42 |
| April | 12°C | 2°C | 40% | 82 |
| May | 17°C | 7°C | 36% | 246 |
In 26 of the 42 March race-weeks measured, the typical overnight low is below freezing — so an early start line can be far colder than the afternoon high suggests.

Planning a spring race from here
A May marathon wants 16 to 18 weeks of training, which puts the start of the block in January or early February. Registration is already open for 69 of the 74 confirmed spring races that publish an opening date, and 4 open later.
