Event Overview
Coast To Kosci is an invitational 240km ultramarathon in southern New South Wales, starting at Twofold Bay near Eden and finishing at Charlotte Pass after a Mt Kosciuszko summit. The next edition is scheduled to start on 20 Nov 2026. The event is organised by runners for runners and has been run since 2004. The field is kept relatively small, with organisers aiming for around 60 starters.
What the Course Demands
The point-to-point format requires athletes to manage steady progress across a full day-and-night effort, with a strict overall time cap noted as up to 46 hours. The route finishes at Charlotte Pass after summiting Mt Kosciuszko, so the later stages include substantial climbing when fatigue is high. Execution hinges on pacing discipline, consistent intake, and maintaining forward momentum through extended low-intensity running and hiking periods.
Who This Event Suits Best
This event suits highly experienced ultramarathon runners who are comfortable with very long durations, variable pacing, and sustained climbing late in the race. As an invitational event with qualifying criteria and limited starters, it best fits athletes with a documented history of completing long ultras. Runners aiming to learn basic ultra logistics or attempting their first long-distance ultra generally need more foundational experience before applying.
