Smurf's Backyard Ultra is set in tropical Cairns, Far North Queensland, Australia. Traversing 6.7km's of the famous Smithfield Mountain Bike Trails, runners tackle a lap on the hour, every hour, until they can no longer continue! Smurf's BYU also includes the Mini Backyard. That's up to 6 laps at a reduced cost! This is an experience, not just an event, also including a bar and food options on the Saturday night to cheer on those still running. This is an atmosphere unique to any other Far North Queensland endurance event!
