The Guzzler Ultra : Brisbane trail races at Mount Coot-Tha
The Guzzler Ultra is a set of trail races held at Mount Coot-Tha in Brisbane and presented by Those Guys Events. The event takes place over two days, 18 to 19 July 2026, and is run almost entirely on singletrack and trail surfaces. The courses pass several of Brisbane's older reservoirs in the order they were built, and local trail running groups staff aid stations and course support.
Race options and key metrics include:
- 105 km: 4618 m elevation gain; 3 reservoirs; 28 hour limit.
- 52 km: 2102 m elevation gain; 2 reservoirs; 12 hour limit.
- 21 km: 711 m elevation gain; 1 reservoir; 4 hour limit.
- 10 km: 399 m elevation gain; 1 reservoir noted; 3.5 hour limit.
The event is recognised as a qualifying race for larger ultrarunning events. It is listed as a Western States qualifying race and as a UTMB index qualifier for some distances. The 50 km and 100 km races are also noted as qualifiers for the Six Foot Track Marathon. Those Guys Events organises and operates the weekend of trail racing with community volunteers and race staff.
