Monarch Ultra 10km
The fourth Monarch Festival & Race is scheduled for September 19, 2026 at Millennium Park in downtown Peterborough, Ontario. The event combines conservation and education with outdoor activity, and includes a festival with live music, local crafts, face painting and information booths.
The main route is an out-and-back 10 km along the TransCanada Trail and Rotary Trail beside the Otonabee River. The course is described as relatively flat. A water station is located at the 5 km turnaround. This is a cup free event; participants must bring their own vessel for volunteers to fill. The 10 km race is chip timed.
A 1 km Kids Fun Run is offered for children under 13. Only 50 spots are available for the kids run. Each child receives a hand-painted medal and a snack at the finish.
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, hydration at the 5 km turnaround, post-race treats and a festival after-party. Prizes are awarded to the top three male and female finishers in the 10 km, for most unique monarch-themed costumes in both distances, and for top fundraisers. Strollers and animals are prohibited on the course by the event insurance. No refunds are issued; if the event is cancelled, entries will be transferred to the 2027 Monarch Race.
