The Monarch Ultra

The Monarch Ultra is a running and conservation initiative that follows the migratory flight of monarch butterflies. The project originated as a 4,300 km (2,671 miles) relay run across three countries: Canada, the United States, and Mexico.

The event schedule includes a Monarch Festival and Race held in Peterborough, Canada, along with trail racing opportunities in Mexico. Participants traverse various environments, ranging from wild landscapes to populated urban areas. The route traditionally starts in southern Ontario and concludes in central Mexico.

The organization focuses on raising awareness for monarch butterflies, whose populations are currently in decline. Beyond the athletic component, the initiative supports local conservation efforts and habitat restoration. For example, the project works with partners such as Nación Verde to address deforestation within the monarch reserve in Mexico. A documentary production also tracks the journey and the environmental challenges faced by these pollinators. Visit the organization's website for the most recent information.
