What Makes It Great

Australia's premier 100km ultra-trail race and the event that has defined UTA since 2008. Starting and finishing at Scenic World in Katoomba, the loop traces cliff tops above the Jamison Valley, descends through lush bushland, climbs the Narrow Neck plateau, descends to the Six Foot Track valley floor, and returns via the Kedumba Pass and Wentworth Falls. The final 951 Furber Steps back to Scenic World have become the most iconic finish in Australian trail running. A UTMB World Series 100K event earning 6 Running Stones.
