Event Overview
Smurf’s Backyard Ultra is held at Smithfield Mountain Bike Park on the north side of Cairns, Queensland, on 24 October 2026. The event uses a backyard-ultra format built around a 6.7km loop, with runners starting a new lap each hour and continuing until they can no longer complete the required loop. A Mini Backyard option is also offered, capped at up to six laps for those targeting a shorter duration.
What the Course Demands
The loop is described as relatively easy trails within the Smithfield MTB Park, but it is not flat. The course includes an opening 1.5km out-and-back section before returning through the event precinct and heading into shaded sections and winding rainforest trails. Per lap elevation is listed as approximately 125m, with small ups and downs across roughly the middle portion of the loop.
Who This Event Suits Best
This event suits runners who prefer structured, repeatable pacing and recovery within a timed format, where consistent lap execution matters as much as speed. The Mini Backyard can fit athletes wanting the same hourly-lap experience without committing to an open-ended duration. With regular elevation each lap, it also aligns with runners comfortable managing rolling terrain over repeated loops.
