  • Completion of an official trail race, 50.00 km or longer between 11:59pm (AEDT) 1 January 2021 and 31 October 2022. You must have finished within the final cut off time for that event. Your result must be for completion of that event. This means, for example, you cannot submit a result showing you made it 55km into a 100km race.
  • You will need to submit a web link to your file/result (e.g. Strava Link or Official Race Website) when you sign up – or modify your entry profile at some later date to include that link. This must be completed before 11:59pm (AEDT) 31 October 2022. Failure to do before this date will result in your entry being cancelled.

There is no pre-requisite of competing or finishing any trail running event to participate in the Kosci100. However, participating in ultra-trail running events will assist with your start group seeding.

All participants of the Kosci100 should be experienced in trail running, including sufficiently skilled and trained to undertake a trail run event. The course is tough, demanding and is remote in sections that can result in slower first aid / rescue response times. It is a combination of fire trail, narrow walking tracks, some very steep sections on staircases, ladders, river/creek crossings, dirt, on rock and sections that are rough under foot.

It is the participants responsibility to ensure you are physically fit enough to complete the distance you have entered and monitor your health and condition during the event, including knowing when to withdraw from the event if you are no longer fit enough to continue.
