Monarch 10k

The Monarch Ultra is back for 2023! After our initial 4,300 kilometre relay from Canada to Mexico in 2019, our 1,800 kilometre relay within Ontario in 2021, we now embark on a series of runs in Canada, the US and Mexico. This year, we have created the Monarch Butterfly Festival and Race which combines conservation, education and activity into one amazing event. Join us for the inaugural Monarch Butterfly Festival andRun at Millennium Park in Peterborough this October!
