Race Distances Offered: 30km & 50km


The Monarch Ultra Relay Run is an 1,800 kilometre running event to raise awareness for monarch butterflies. Starting in Peterborough on September 19th, 2021 and heading south towards Toronto, Burlington, Hamilton, St. Catharines, and Niagara Falls, then running southwest along Lake Erie, looping back around towards London, Cambridge, and Kitchener, and ending in Barrie on October 9, 2021. Relay runners, running in pairs when possible, will run approximately 30km and 50km segments over 21 days through a variety of landscapes – dedicated trails, urban, rural and wilderness, and along greenways, waterways and roadways of the Great Trail and Waterfront Trail. The running event is entirely organized by a volunteer team who are passionate about protecting the Earth and are on a mission to inspire communities to get involved in conservation action! Not only will this be one of the Canada’s longest relay runs, it will also be an ultra-memorable experience for everyone involved. Running fast is optional but having fun is guaranteed! Most importantly, the Monarch Ultra is an opportunity to connect communities across Ontario with common goals of Earth stewardship and biodiversity conservation.
