Upcoming challenges.

The IRONMAN Virtual Club is hosting a series of challenges to give you a taste of the event day that will be announced in the coming days. Sign up to the IRONMAN VC to find out more.

  • FulGaz St George Ride Challenge – 4 x Segments with GC Leaderboard / 180km in one ride (Open from 1 – 10 May) (Ride only)
  • Full 180km Bike leg – open for 10 Day IRONMAN Challenge – Open from 1 – 10 May (Commences 6 AM Utah Time) (Swim/bike/run)
  • Brick Workout – Using Segment/stage 4 of Utah Course – 7th May (Opens 6 AM Utah Time) (Ride/run)

The official bike route has been broken up into four stages, so you don’t have to slog through the full 180km on one go. You can ride these in any order, just make sure that you finish BEFORE the cut-off times.

The route is a stunning journey through the deserts of Arizona, taking in views of the Red Cliffs National Conversation area. When racing, take a moment to look up and take in the stunning countryside.

This is a free event for FulGaz subscribers.

New to FulGaz? Here's the quick start guide.

1. Download FulGaz and set up a free account
We’re offering all new subscribers a 14-day free trial, no credit card required.

Downloading the trial gives you full access to FulGaz with no restrictions on content, or how often or how far you ride. If you’re returning to FulGaz for another go, send us a support ticket and we’ll hook you up with another trial on the house.

2. Connect your devices
When you load up FulGaz and hit Get Started, you’ll be greeted with a pairing screen. Here your smart bike/trainer/speed sensor will be picked up and listed. Select the devices you’d like to connect and click Let’s Ride.

Pro Tip If you can’t see your devices when trying to connect, they are most likely paired with another app (RGT, Rouvy, Zwift). You will need to deselect your trainer from that app’s pairing screen, quit that app, and restart FulGaz.

3. Set your preferences, weight and slope scaling
Click the settings icon to take a moment to set your display preference (metric or imperial). For the most realistic experience, enter your weight and bike weight. There are many other settings here also; it’s best to get a feel for riding FulGaz first before adjusting these. Start at around 60% uphill to get the feel. You can adjust this in ride also.

Pro Tip If you find the hills too hard, you can adjust the Slope Scaling, this is essentially the “trainer difficulty”. Adjusting this won’t make you faster, but it will make hills easier!

4. Download a video and ride
We always suggest downloading the video ahead of time. For any event you must download the video.  Before the event, test your set up with something from the Easy collection. These rides will give you a good “feel” for how FulGaz looks and interacts with your trainer or smart bike.

5. Get event-ready
Before you start your event, make sure you turn up at the start line ready.

Here’s a quick checklist

      • Download the ride ahead of time
      • If joining us on Zoom, download the app and run it on a different device.
      • Stay hydrated – have at least two bottles of water available
      • Have a towel and fan to help you cool down.
What equipment do I need?

To participate in this event from the comfort of your own home you will need some cycling equipment.

PRO Set-Up

  • Road Bike
  • Smart Trainer (e.g, Wahoo Kickr) or a smart bike.

Connection equipment

FulGaz works on Apple TV, MacOS or an iPhone or iPad as well as Windows and Android devices. To get started you will need to download the app onto your respective device. For an amazing viewing (and riding) experience we highly recommend using an Apple TV connected to your lounge room TV or monitor.

Do I have to ride these in order?

You can ride these routes in any order you like, just make sure you finish before the cutoffs.

You can ride the routes multiple times but remember FulGaz will only record your most recent attempt on the leaderboard.

How similar are the bike courses in FulGaz to the actual events?
