Lucas Trihey – Owner

Lucas has worked in the adventure world for 30+ years and has experience in expeditions, remote events, film crew support, safety and risk consulting, medical teams, adventure events and conferences, adventure publishing and editing. His work has included training people to work in remote areas, adventure guides, roped activities, emergency response and retail.

Lucas is the medical team director for Ultra Trail Australia (“UTA”, previously known as North Face 100) and Coastrek NSW. He spent four years as course designer, rigger and safety director for The Test of the Toughest and he was the Australian team leader for the safety and rigging team at the 1997 Eco-Challenge. He is currently the medical team director for Coastrek, the Buffalo Stampede, 4-Peaks, Hounslow Classic, Glow Worm Tunnel Marathon, Kanangra Classic and the NSW Running Wild Series. He is Event Director for the 250km, 6-day Big Red Run and Big Red Bash in the Simpson Desert and Trek Director for the 11-day, 330km Burke and Wills Trek in the outback. He is Safety and Medical Director for the ANZAC Day Challenge. He rigged the rope climb/descent at the 2014 GeoQuest in the Flinders Ranges and sets up the Tarros Ladder bypass every year for Wild Endurance and UTA. Film production credits include The Edge (IMAX), Test of the Toughest, Rexona Australia’s Greatest Athlete, All About E and numerous docos and TVCs over 20 years.

Lucas advises and consults on risk management and event safety and has worked with the Victorian Rogaining Association, Birdsville Race Club and the Kep Track Ultra. He is a logistics and communications adviser and guest lecturer for Expedition and Wilderness Medicine. In 2006 he was the first person to walk across the Simpson Desert unsupported and avoiding 4WD tracks. The 17-day 400km trek was completed pulling a cart with all water and food and involved crossing 1000 dunes.

Recreationally Lucas has climbed rocks and mountains around the world, joined and led expeditions to far-flung places and he’s walked and driven across many of Australia’s deserts. Lucas was one of the founders of the Blue Mountains Climber’s Rescue Group and Australian Accident Register. He spent a lot of the 90s pioneering new rock climbs in his local Blue Mountains, spent a few summers ice-climbing in NZ and was the first Australian to fly a paraglider from the top of Mt Cook/Aoraki. To help pay off his first house he drove trucks and ran a tree-lopping business in between adventure work. He’s been bogged to the axles many times, has fixed broken-down cars in the outback and loves nothing more than a bush-mechanic challenge. From 2002 to 2008 he published and edited Outdoor Australia, Adventure Gear Guide and Adventure Journal.
