152km across three days — Bright's complete trail running gauntlet



Australia's ultimate trail weekend challenge: complete the full trilogy of the 10km Twilight, 100km Bright Ultra, and 42km Skymarathon across three consecutive days for a combined 152km of alpine running. The Ultra Slam demands extraordinary recovery and back-to-back-to-back racing, with a critical shuttle deadline after the 100km — runners must finish the Saturday race before 5am to board the 5:20am shuttle to the 42km start.
