The Guzzler Ultra is Brisbane's very own ultramarathon trail running event. Choose your option: the main Guzzler (100 kilometre), the Glass Half Full (50 kilometre) or the Big Sipper (21 kilometre). 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, Gold Creek Reservoir and Lake Manchester before skipping (or dragging) your way back home to a vibrant and welcoming finish line. If you prefer your Glass Half Full, you can tackle the 50 kilometre event which will take in the first two reservoirs, Enoggera and Gold Creek or test the water with the Big Sipper, which swings past Enoggera Reservoir. It's all trails, all fun and all challenge - all from the heart of a major capital city!
