Shannon, Ireland – March 12th, 2025 – Kleos Aero, a leading provider of flight planning, trip management, and concierge services, is proud to announce its role as the official logistics partner for Jason Williamson’s upcoming challenge – a 4,000km ultra-marathon across Australia.
Williamson, the founder of Six West Aviation and an accomplished ultra-marathon runner, is embarking on this extraordinary endurance challenge to push the limits of human performance in celebration of his upcoming 50th birthday. With extensive experience in aviation logistics and operational efficiency, Kleos Aero will be responsible for the comprehensive planning and coordination of all logistical aspects of the 4,000km journey.
“Our expertise in managing complex global operations translates seamlessly into supporting Jason’s remarkable challenge.” said Paul Cantillon, Board Member at Kleos Aero. “From route planning and real-time tracking to accommodation, transport and on-the-ground coordination, we are dedicated to ensuring a smooth and efficient execution of this inspirational feat.”
The extreme ultra marathon will take Jason through some of the most demanding and remote terrains in Australia, testing his endurance across deserts, mountains, bushland and more in extreme weather conditions. Jason will take on the extraordinary challenge of running two marathons a day for 50 consecutive days, covering the vast 4,000km distance from Perth, Western Australia, to his hometown of Port Macquarie, New South Wales—traversing the entire width of Australia.
Kleos Aero’s team will apply its precision planning and resource management capabilities to facilitate seamless transitions at each stage of the journey, allowing Jason to focus solely on his performance.
“As an aviation professional, I’ve always valued meticulous planning and resilience – qualities that are equally crucial in endurance sports.” said Jason Williamson. “Having Kleos Aero handle the logistics gives me complete confidence that every aspect of this challenge will be expertly managed, allowing me to concentrate on the miles ahead.”
Kleos Aero continues to expand its niche service offerings, demonstrating its adaptability beyond the aviation sector by leveraging its expertise to support high-performance endeavours in extreme environments.
