The Guzzler Ultra Trail Running Festival

The Guzzler Ultra Trail Running Festival returns to Mt Coot-tha, Brisbane from 18 to 19 July 2026. Choose your option: the Guzzler (100km), the Glass Half Full (50km), the Big Sipper (21km) or the Dry Run (10km). The Guzzler heads out from the green heart of Brisbane, Mt Coot-tha, to visit three of Brisbane’s oldest reservoirs. You’ll take a trip through history, running past Enoggera Reservoir, opened in 1866, followed by Gold Creek Reservoir, opened 1882, before seeking out Lake Manchester, opened in 1916. From there you'll skip (or drag) your way home to a tall glass of Brisbane's finest (water)! If you prefer your Glass Half Full, you can tackle the 50km event which will take in the first two reservoirs, Enoggera and Gold Creek.
