Overview

Taking runners from Eden, NSW to Australia's highest peak at Mt Kosciuszko, the Coast to Kosci Ultramarathon covers 240 km with a 48-hour time limit. The required pace of 12 minutes per kilometre makes the cut-off tighter than 76% of 200mi+ races and more generous than 24%, demanding sustained forward movement across two full days without giving leeway for extended rest stops.

Despite an overall elevation gain of 2500 metres to the 2228-metre summit, the route averages a modest 10.4 metres of climb per kilometre, meaning large sections can be run at pace rather than hiked. The event features a field bigger than 82% of its peer group and smaller than 14%, having seen 47 finishers at its 2025 edition across 10 held editions since 2014.
