Monarch Ultra

Monarch Ultra 10km is held in Peterborough, Ontario, starting and finishing at Millennium Park in downtown Peterborough. The 10K course is an out-and-back along the Rotary Trail beside the Otonabee River, described as flat and fast. The event also offers a 1K Kids Fun Run, with chip timing for the 10K and a cup-free water station at the 5K turnaround.

Participants are encouraged to wear Monarch-themed costumes, with prizes for creativity, and a post-race Monarch Festival featuring live music, crafts, food, and educational booths. Proceeds support Camp Kawartha through fundraising. The festival celebrates conservation and community, combining sport, education, and family-friendly activities as Monarch Festival & Race.
