Mad Trapper Backyard Ultra

Mad Trapper Backyard Ultra is held on the trails at The Ark in Denholm, Quebec. The event offers an individual Last Person Standing format, a two person team option, and a winter snowshoe version. Runners must return to a central corral each hour and be present when the audio call signals the next lap to continue. The individual winner is the last person to complete a full loop solo.

Distances vary by course and season:

  • Full course about 5.5 to 6.0 km in summer
  • Kristi Loop about 500 m shorter, around 5 km in summer
  • Winter full course 5.5 km, Kristi Loop under 5 km

The two person team race uses the Kristi Loop and has Friends and Couples categories. A racer is out if unable to complete a lap within an hour; the team continues until both members are out. Teams face a 16 hour cutoff or the duration of the individual event. Prizes are awarded for full and Kristi Loop winners.

Registered Backyard Ultra runners can camp free at The Ark in a rustic wilderness site with flat tenting areas, outhouses, a firepit, picnic table, and drinking water. The organizer provides water, an electrolyte drink, and some food on race day. An indoor transition area is available for the snowshoe edition.
