The Guzzler Ultra is a multi-distance trail running event held at Mt Coot-Tha, Brisbane, organised by Those Guys Events. The courses are almost entirely on trails and pass a sequence of Brisbane’s oldest reservoirs in the order they were built. Local trail running groups and volunteers support aid and on-course logistics.

The event offers several race options with published distance, elevation gain, reservoir count and nominal finish times:

  • 105 km distance, 4618 m elevation gain, visits 3 reservoirs, time to finish 28 hrs
  • 52 km distance, 2102 m elevation gain, visits 2 reservoirs, time to finish 12 hrs
  • 21 km distance, 711 m elevation gain, visits 1 reservoir, time to finish 4 hrs
  • 10 km distance, 399 m elevation gain, visits 1 reservoir, time to finish 3.5 hrs

The event is recognised as a qualifying race for several international and national events. Specific race categories are listed as qualifiers for Western States, UTMB Index entry, and as a qualifier for the Six Foot Track Marathon in the 50 km and 100 km distances. The organiser’s program includes course information, mandatory gear lists, and athlete resources. Visit the organization's website for the most recent information.
