Monarch Ultra 10km and Monarch Festival
The fourth annual Monarch Festival and Race takes place in Peterborough on September 19, 2026, at Millennium Park, 130 King Street. The event combines a road race, a kids run, a festival and fundraising for monarch conservation.
The main event is a 10 km out and back route along the Rotary Trail and the TransCanada Trail. The course is described as relatively flat. A water station is located at the 5 km turnaround. The 10 km is chip timed. This is a cup free event so participants must bring their own handheld or bottle. Top three male and top three female finishers in the 10 km receive prizes. Additional prizes are awarded for most unique monarch-themed costumes and for top fundraisers.
A 1 km Kids Fun Run for children under 13 starts and finishes at Millennium Park. Only 50 spots are available for the kids run; each child receives a hand painted medal and a snack.
Registration includes a race bib, a monarch inspired neck gaiter for 10 km finishers, a custom medal for 1 km finishers, milkweed seeds, chip timing, post-race refreshments and on-site festival activities. The event policy forbids strollers and animals on the course. No refunds are offered; if the event is canceled, participants will be transferred to the 2027 Monarch Race.
