Monarch Ultra 10km

The Monarch Ultra is planning Peterborough’s second annual Monarch Butterfly Festival and 10km Race this fall at Millennium Park. The 10km race will start at Millennium Park and will wind along the Rotary Trail and back. The race will also be an opportunity to fundraise for the conservation of monarch sanctuaries in central Mexico. We will be working closely with our Mexican partners to support reforestation efforts in the Monarch Butterfly Biosphere Reserve.
