The event is the pinnacle of trail runs in Australia. A challenging, spectacular course through some of Australia’s most iconic landscape of the Blue Mountains. 100km was never meant to be easy and this course will certainly test even the best. But it will bring great rewards, phenomenal views, and the best tracks in the Blue Mountains. If you can finish the full 100km in under 20 hours you will become an exclusive member of the TNF 100 club and receive a special memento.
