Canada's shortest ultra hides a monster secret

At 43 km, this is officially Canada's shortest ultramarathon. But with backcountry sections up to 17 km between aid stations and Mazinaw Rock rising 100 m from Ontario's second deepest lake, it earns every metre of its name.


Highlights

  • Run past Canada's largest rock art site on the Shield

  • 43km race that feels way, way longer than it sounds

  • Race around a lake hiding a rumoured ancient lake creature

  • Up to 17km between aid stations on raw backcountry terrain

  • Spectacular September foliage through Bon Echo Provincial Park
