Monarch Ultra 10km
The fourth annual Monarch Festival & Race takes place on September 19, 2026, at Millennium Park in downtown Peterborough, Ontario. The event combines a running program with a festival focused on monarch butterfly conservation, featuring live music, local crafts, face painting, informational booths, guest speakers, and food vendors.
Distances offered:
- 10 km
- 1 km Kids Fun Run (under 13 years, 50 spots)
The 10 km is an out-and-back route along the Rotary Trail and the TransCanada Trail beside the Otonabee River. The course is described as relatively flat and includes a water station at the 5 km turnaround. This is a cup free event; participants must bring their own vessel for refills. The 10 km race uses chip timing. Prizes will be presented to the top three finishers in male and female categories, and costume prizes will be awarded in both distances. Additional prizes will recognize top fundraisers.
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 an after-party. No refunds; if the event is cancelled, participants will be transferred to the 2027 Monarch Race. Strollers and animals are prohibited on the race course.
