19th—20th July 2025
Course Description
While The Guzzler is the main event of the weekend, the Glass Half Full packs a punch of its own, taking you around some spectacular and challenging trails. We’ll show you what locals know and love about our green city, just how much fun and how much nature you can reach directly from Mt Coot-tha, completely on foot, completely on trails! You’ll tour two of our reservoirs in the order they were built, soaking up fire trails, single track, rolling hills and some mean ones too! Let us take you on an adventure in our backyard.

Segments
We have thrown down one ripper challenge for you all: the ‘Hell Hole Hustle’. The fastest guy and gal to make it through Hell Hole will each win everlasting fame and fortune as well as an awesome prize pack*.
The Hell Hole Hustle will present you with quandry. Do you go all out through this section to get the crown.. or do you pace yourself and chase overall Guzzler glory?
And as though the bragging rights weren’t enough, we have put a prize pack on the line – one each for the Hustle King & Queen!
The Hustle stats:
- Starts: Exit of McAfees Lookout Checkpoint
- Ends: End of Hell Hole Break (exit onto South Boundary Rd).
- Distance: 3.3km
- Descent: 243m
- Ascent: 176m
Check out the Strava segment and KOM below.
*Fame and fortune not guaranteed.
*Please note: the Strava segment has been made slightly shorter than the event day Hustle. This was done to allow everyone to compare their times during training without worrying abut GPS inaccuracy. Event day results will be tracked via live timing mats at the start and finish of the race segment.
- There will be two winners. ONE female GRITtiest girl and ONE male GRITtiest guy.
- Winners will be the fastest person of their gender to complete the timed Hell Hole Hustle (HHH) section of The Guzzler / The Glass Half Full, as determined by our electronic race timing system, or manual timing backup in accordance with the race gun time. Placement of the electronic timing mats will be fixed throughout the duration of the race to create a fair and comparable HHH split time.
- One winner per gender will be determined from all runners across the Guzzler AND Glass Half Full. For example the fastest runner in The Guzzler may later be beaten by a faster runner in The Glass Half Full, if their HHH split time is shorter.
- To qualify to win the HHH, the racer MUST complete the whole of their registered event, within the designated race cut-off times, as per the race rules. If the fastest HHH racer later withdraws or is disqualified for any reason, the HHH title will roll down to the next eligible competitor.
- The HHH winner does not need to be the overall race winner of their registered event.
- Play nicely! Any pushing, jostling, obstructing of members of the public or other anti-social behaviour may see you disqualified from the HHH or potentially the whole event.
- While live tracking of the HHH will be available, we reserve the right to adjust the segment times of runners if required due to calibration or any other error of the live timing system.
Mandatory Gear
While we hope you have nothing but fun on The Guzzler course, sometimes things go wrong. The mandatory gear that every runner must carry will help reduce the risk of anything happening or, if it does, will improve your chances of a smooth rescue and recovery.
Please note, mandatory gear is gear you MUST carry. For you comfort, please consider the weather conditions on race day and carry whatever gear you feel you need to keep you happy through the event.
Click on each item if you’d like more details and feel free to contact us at The Trail Co. if you’d like more guidance.
Key
MandatoryRequired in some situations
Recommended
This may be in the form of a reservoir, soft flasks, bottles or any combination of these.
You don’t need to have 2L of water in there at all times (after all – you should be drinking it!) but do need to be able to carry that much to ensure you can safely complete the distance between each checkpoint.
Will be supplied at registration. Bibs must be visible on your front at all times for the timing chip to work and for your safety.
Bibs will include your timing chip, your name (for early entries), and a unique number.
Every runner must carry a working mobile phone. Please ensure it is fully charged before starting the Event and that emergency and event phone numbers are saved and easily accessible.
For international guests, you may need to purchase an Australian SIM to use during the event or may be able to access an Australian network using roaming.
In case we need to contact you while you are out on course, please log back in to the registration platform prior to race day and ensure the number of the phone you intend to carry is up to date in the Event Contact Details section.
Recommended:
Dry Sacks will keep your gear protected from rain and sweat, protecting it from damage and ensuring it will be dry if you need to put any of it on.
You can use one large sack or several small ones. Zip lock bags are acceptable if they are in good condition and can be fully sealed.
Recommended:
All runners carry a headlight, regardless as to whether you think you’ll be running in the dark. If you become lost, ill or injured, you may be out there much longer than intended.
A minimum brightness of 300 lumens is recommended so you can confidently run through the bush. However, for the 50km, if you expect to arrive well before nightfall a smaller light just in case of emergencies will be fine.
As a minimum, the compression bandage must a heavy-weight, crepe bandage that is 7.5cm wide x 2.3m long (when unstretched).
Recommended:
Conforming Heavyweight Crepe BandageIt must not use a ‘pea’ to create a sound as these can become sticky when damp causing the whistle to fail – that means no sports whistles.
Many running packs include a whistle and The Trail Co. also sells some small, inexpensive whistles that can be attached to your pack.
Recommended:
Emergency BlanketsAll runners must carry the course map loaded in the Maps.Me application on you mobile device.
maps.me allows you to find your location in relation to your current position even if no cell reception is available.
Please test this application and the map well in advance of the event weekend.
The following video is our guide on how to use Maps.me to navigate the course and share your location. There is also an iphone and Android guide to importing a map (bookmarks) here if you would like a written guide.

This must be a long-sleeved, thermal base layer made of polypropylene or wool which will keep the participant warm in addition to their race clothing.
Cotton, Coolmax, lycra, compression garments and thermal compression garments are NOT suitable to be used as the ‘Thermal Top’.
An extra portion of food (eg gel, bar, sandwich), must be carried at all times in addition to the fuel you intend to use if all goes to plan.
This extra portion may prove vital if you are ill or injured and find yourself taking longer to reach the next checkpoint than expected, or if you are waiting some time for aid to reach you.
If heavy rain is predicted, runners will need to carry a Waterproof Jacket. We will inform you the afternoon before Event day, via email, if these become a mandatory item.
A good-quality waterproof jacket will keep you dry while allowing sweat to escape. It can also be useful for added warmth or protection from the wind.
At a minimum, the jacket must fit you and be fully seam-sealed, waterproof, and not include any large mesh vents, even if covered by flaps. Minimal underarm vents are allowed.
All checkpoints are cup-free so if you’d like to have some soft drink, you may want to bring a cup along instead of using your water flasks.
Always recommended. Sunburn is nobody’s idea of a good time!
Slip, slop, slap!
If temperatures are expected to be low, or you think you may find yourself walking during the race, your energy expenditure may not be high enough to keep your core temperature up. A synthetic fleece is lightweight and can be very effective at keeping you warm.
Please carefully consider carrying a fleece for your comfort and safety.
The event will proceed in the rain. If heavy rain is predicted we recommend that you carry Waterproof Pants.
While mandatory in some situations for the 100km runners, 50km runners can choose to take these or not.
