Oakville 21.1 2026

The Nutrience Oakville 21.1 Half Marathon takes place in October in Oakville, Ontario — organized by Endurance Event Productions and returning for its second year under that banner. Endurance Event Productions has built a reputation for well-run waterfront races in Ontario since launching in 2021, and Oakville’s half arrives as a highlight of the fall running calendar for the town.

Race day offers a half marathon (21.1K) plus 10K and 5K distances, with event timing on October 4 that begins at 7:30 a.m. and runs through the morning. All distances use the same lakeside corridor, so spectators and crew can see runners across multiple distances without moving far from the start/finish area.

What sets Oakville 21.1 apart is its flat, fast and scenic Lakeshore Road routing. The course hugs the waterfront for long stretches and threads through familiar Oakville streets, making it a favourite for runners chasing fast times and lively crowd support. Local partners and sponsors — including Nutrience and area automotive supporters — help bring a strong community presence on race day, and previous editions attracted a large, energetic field.
