Rainbow Trail Run 2026

The Rainbow Trail Run takes place on June 13, 2026 in Simcoe County, Ontario and is now organized by OFFBEAT Running. The race follows a familiar summer date in the region and continues a recent run of editions held at Earl Rowe Provincial Park.

​

The event is run as an approximately 12K single-loop through Earl Rowe Provincial Park. The course circles sections of Earl Rowe Lake and stays mostly on wide trail corridors, offering a compact, straightforward format that fits into a single morning of racing.

​

What sets Rainbow Trail Run apart is its mix of easy-going trail terrain and a few standout features: multiple bridge crossings over Earl Rowe Lake, a short climb up to a lookout that makes for a reliable photo stop, and largely flat running that keeps the effort approachable. OFFBEAT Running’s stewardship brings a community-oriented feel, and the race links into local Visit Dufferin partners so runners can make a day or overnight of exploring the region.

​

Registration is handled through Race Roster; follow the event’s Race Roster registration to secure a spot for the June race.
