Smurf's Backyard Ultra : Cairns, Australia

Smurf's Backyard Ultra is an endurance running event held at Smithfield Mountain Bike Park in Cairns, Far North Queensland. Runners complete a loop of the Smithfield Mountain Bike Trails each hour, repeating the 6.7 km circuit until only one participant continues.

The event uses the mountain bike trail terrain and is organised by Smurf Endurance Sports. A shorter option called Mini Backyard allows participants to complete up to six laps instead of continuing until a single finisher remains.

The event program includes a Saturday night gathering with food, drinks, a bar and live music. The race is presented as a format where laps are repeated on an hourly schedule and distance accumulates by number of laps completed.

Practical details noted for the event include the location at Smithfield MTB Park in tropical Cairns and that entries for the 2026 edition are available. The format emphasises repeated 6.7 km laps on established trails and an on site social component during the weekend. Visit the organization's website for the most recent information.
