While you're not required to demonstrate any previous experience with trail and/or ultramarathon running in order to enter the Guzzler, it is expected that you will have trained on terrain that is similar to that which you will experience during the Event and that you have done sufficient training to prepare you for an ultramarathon. You must ensure that, on race day, you are sufficiently fit and healthy to complete the Event within the official cut-off times.


While working through registration, you'll need to provide personal details and answer a few questions such as:

  • Personal details: eg name, DOB, address etc
  • Nickname: as you'd like it to appear on your bib
  • Country of representation
  • Race day contact details: the phone we'll be able to call you on during the event. 
  • Emergency contact details: must be someone who is not registered in either the 50km or 100km Event
  • Medical history: providing details about current or recent illnesses, hospital stays and other important information that may help medical professionals provide care to you in an emergency.
  • Event T-Shirt size: check out the sizing chart here
  • Agree to the Release Waiver and Conditions of Entry: these can be read here

You will be able to log back into your EventPlus profile and update some of these details if they change between the time of entry and the Event.

If you have entered another event that uses the EventPlus registration platform (eg Ultra-Trail Australia, Tarawera Ultra and more), you will already have an athlete profile, making registration even easier!
