Delirious West

Delirious WEST is Ultra Series Australia’s epic trail ultramarathon across Western Australia’s Bibbulmun Track, from Northcliffe to Albany. The event offers a 170–340 km option and two race lengths: a 100 Miler and a 200 Miler, typically finishing in Albany after a week of rugged endurance. Celebrated as one of the world’s top 10 hardest 200-milers, the course features towering forests, dramatic ocean cliffs, dunes, and treetop walks, with additional sights like beaches and jet ski crossings and shuttle-bus support. Runners rely on extensive aid and sleep stations, stage-by-stage planning, mandatory gear, live tracking, and a volunteer-driven atmosphere that’s soul-defining.
