Course Description

Leaving from the heart of Brissie trails, Mt Coot-tha, The Guzzler Ultra 100km trail run takes you on an adventure like no other. We take you on tour of some of The Trail Co.’s favourite routes; to beautiful reservoirs, up challenging hills and along single track that will have you flying fast and free, like a kid on the first day of school holidays. You’ll need good training, a dash of humour and a pair of well prepared legs for this little run. Don’t be lulled by The Guzzler’s cheeky nature. She’ll test you!

The Guzzler is 99.9% trails, 100% FUN!

See Checkpoints below for more details about these.

GPS Trackers

100km runners will have a personal GPS tracking device which will record their progress around the course so that supporters and crew can follow them with ease.

100km runners must collect their allocated GPS tracker from the race precinct prior to starting the event, and must return it after they have finished, before going home. Please note that runners or their crew MUST return the tracker to the race precinct before 10:30am Sunday, even if the runner withdraws from the event.
