Subaru Tri Series

Subaru Triathlon Series is an Ontario-based multisport event organizer that hosts triathlons and duathlons for athletes of all ages and abilities. Its goal is to encourage physical activity, introduce people to outdoor sport, and make racing welcoming to newcomers as well as experienced competitors. The series emphasizes friendly course designs, reasonable cut-off times, thoughtful event planning, and spectator-friendly venues, while still offering opportunities for athletes to compete at a high level.

The 2026 race lineup includes events in Milton, Guelph, Niagara (Grimsby), and Owen Sound. The organization also highlights partner events, including the Subaru Women’s Triathlon Festival, IRONMAN 70.3 Muskoka, and the Niagara Falls Marathon. Participants can find registration information, results, series points, a beginner’s guide, and volunteer details through the series website. Race amenities vary by event but may include on-course aid stations and post-race nutrition. Registrants receive an event shirt and finisher’s medal, with medals also awarded to podium finishers. Subaru Canada is identified as a partner of the series.
