ULTRA355 Hervey Bay – Race Overview

Triathlon enthusiasts looking for their next big challenge should look no further than the ULTRA355 triathlon series. Our newest addition, taking place in the beautiful state of Queensland, Australia, offers participants an unforgettable experience. Over three exhilarating days, athletes will push their limits in a swim, bike, and run adventure that tests their physical and mental endurance. ULTRA355’s unique format allows competitors to enjoy the camaraderie of the triathlon community while tackling a race specifically designed to offer a one-of-a-kind experience.

You will start your 355 Australia journey with registration and meeting the crew and other athletes at the race precinct on the Friday of race weekend. Check out the Urangan Pier, which is your swim finish on Saturday. The start of your 5km swim on Saturday will be at Scarness, leaving you a magic 5km point-to-point swim with some helpful tide assistance. Head off on our challenging bike course for 2 60km laps, starting off in closed road conditions for your safety. Day 2 sees you taking on three laps of the course to give you the 180km challenge in your 8-hour cutoff. On day 3, you will complete the 50km run within sight of the water along the shaded Esplanade foreshore path. Four laps of the course and an unforgettable finish await you with a bit of out-and-back on the iconic Pier before you savor that finish line feeling.

ULTRA355 Australia – 2024 Schedule

Day 1: Swim and Bike

You’ll be surrounded by fellow athletes who share your passion and drive throughout both portions.

Day 2: Long-Distance Bike Ride
Day two is even more demanding, with a 180k bike ride that will truly test your limits. This portion of the event will push your endurance to new heights and leave you feeling accomplished and proud.

On the final day of the ULTRA355 triathlon, you’ll embark on a scenic 50km run along the picturesque Hervey Bay esplanade path. Spectators will have numerous fantastic vantage points to cheer you on while indulging in a delightful coffee, breakfast, or even ice cream as you show your mettle. The 12km loop from Urangan to Pialba, shaded by trees, takes you all the way to the epic finish, where you can capture that well-deserved photo crossing the finish line, proudly holding the finish tape you’ve worked tirelessly for!

ULTRA355 Australia Triathlon FAQ

What is the cutoff time for each day?

  • You will have 8-hours from the start time

What does Self-supported mean?

  • You will look after yourself during the race regarding hydration and nutrition, with help from your special needs bags and some basic aid stations from race organisers.

So do I need a crew?

  • No. There are no crews in ULTRA355, your supporters can be out there cheering on the course, but they can’t assist you with nutrition or hydration. This is considered outside assistance and could be penalised.

What is supplied at the aid stations?

  • Water will only be supplied at the aid stations, generally in the form of a large cooler to refill your water bottle/hydration systems. Our crew manning the aid stations will help you with this.

How often can I access my special needs?

  • Your special needs bags will be accessible in the T1 area on day one when you transition and at the 60km mark halfway through your ride. On day 2, you will again see your special needs at 60 and then 120 as you complete the 3 laps. On day 3, you will pass the special needs area at the 12, 24, and 36km mark.

Is there a limit to what I can put in special needs?

  • You will need to use the bag supplied by us, just so we know we can fit everyone’s supplies in, but fill that bag with all your treats as much as you wish!

Can I have a pacer on the run?

  • No, we don’t allow pacers for any part of the race at ULTRA355.

Will I need any nutrition on the swim?

  • With the 5km swim, it’s only marginally longer than your usual IM swim. You are welcome to use a tow float which often has storage compartments. None of the ULTRA355 races have accessible nutrition locations during the swim.
