Event Overview
The Kangaroo Island Marathon is held on Sunday 23 August 2026 within Flinders Chase National Park, South Australia. The program includes the KI50 (50km), marathon (42.2km), half-marathon (21.1km) and the SeaLink 10km. Start locations vary by distance, with finishes at the Flinders Chase Visitors Centre. The event has operated since 2015 and is conducted on Karta Pintingga Country, using routes that visit landmarks such as Remarkable Rocks.
What the Course Demands
Across the weekend distances, the routes combine long, uninterrupted sections through Flinders Chase with out-and-back and point-to-point formats depending on the race. The KI50 follows the marathon’s Remarkable Rocks leg and adds repeated out-and-back segments to Admirals Arch. The marathon and 10km start near the park entrance, while the half-marathon starts at Remarkable Rocks with a provided bus transfer for runners.
Who This Event Suits Best
This event suits runners who value remote-event logistics and are comfortable with extended time on course, including strict cut-off times that vary by distance. The 10km is accessible for newer participants (minimum age 10), while the half-marathon (minimum age 14) supports developing endurance with a point-to-point format. The marathon and KI50 (minimum age 18) are better suited to experienced runners planning for sustained effort.
