The Guzzler Ultra is Brisbane’s signature trail running festival, taking place over the weekend of July 19–20, 2025, in the scenic Mt Coot-tha Forest. This renowned event offers four race options: a grueling 105km ultra with 4,618 meters of elevation gain, a demanding 52km course with 2,102 meters of gain, a tough 21km half marathon, and a more accessible 10km option for beginners. Runners navigate rugged trails past historic reservoirs including Enoggera, Gold Creek, and Lake Manchester, with stunning views, creek crossings, and technical climbs. Fully stocked aid stations, strong community support, and UTMB/Western States qualifier status make this a bucket-list race for trail enthusiasts. All distances start and finish at Mt Coot-tha, creating an electric festival atmosphere across the weekend.
