From racing my first HYROX in Sydney in 2024, I never could have imagined that two years later I’d be lining up alongside the athletes who inspired me to pursue this sport.

To now have the opportunity to compete against the best in the world at the World Championships is something I’m incredibly grateful for. A lot of hard work, sacrifice and support have gone into getting to this point, and I’m excited to see what I’m capable of on the biggest stage.

A huge thank you to my family and friends back home, and to my sponsors for their continued support throughout the journey. I wouldn’t be here without you.

Let’s GO! 🚀

Just over 3 weeks out from HYROX Worlds in Stockholm and my Elite 15 Solo race 🇸🇪

I’ve consistently been using .hydrate to stay on top of fluid balance by replacing what’s lost in sweat. It’s not just water, but key electrolytes like sodium that help the body absorb and retain fluid properly.

When training volume and intensity are high, that balance matters. Better recovery between sessions, more stable output across the week, and feeling ready to go again day after day.

Current favourites: Lemon Yuzu + Green Apple 🍋🍏
Also rate Strawberry Kiwi and Raspberry 👌

It’s become a non-negotiable part of the daily routine 🤝

Noosa 10K ☀️🏃‍♂️

Time: 34:32 (3:27/km)

Nice to get a 10K PB in with big daddy before Stockholm in some challenging conditions. Felt solid and controlled throughout. Keen to have another crack at this sometime and target sub-34.

Another awesome event from and well done to everyone for getting after it 🙌

3.5 weeks until go time 🇸🇪

How I shaved 5 minutes off my HYROX time and broke into the Elite 15 👊🏽

1. Following a structured program: Including easy days to allow the body to recover, adapt to the training stimulus and continue building volume consistently. Recovering between sessions meant I could hit the required intensity on key workouts and continue progressing instead of just accumulating fatigue.

2. Threshold training: Using running, machine work and station-specific efforts that replicate the physiological demands of race day. These sessions typically include structured intervals at or around threshold intensity, often using a 5:1 or 4:1 work-to-rest ratio to accumulate time under high but sustainable metabolic stress.

3. Strength training and mobility: Improving force production, movement efficiency and resilience. This reduced injury risk and increased my ability to handle heavy sleds and maintain movement quality under fatigue.

4. Working on weaknesses: My biggest ones from my first HYROX race were running, burpees, lunges and wall balls. One of the biggest advantages we get in HYROX is the race data and feedback after each event, making it very clear where the gaps are. Deliberately focusing on these areas has been huge for progress. Over time, weaknesses start to turn into strengths and that’s where massive improvements happen.

5. Commit to a schedule you can actually sustain long term. For me personally that’s 8–10 hours per week alongside business and family. Pushing beyond that would compromise recovery, consistency and other important areas of life. Consistency over time has always mattered more than volume spikes. Don’t get caught comparing yourself to what others are doing on social media. What you can recover from and repeat week after week is what drives adaptation.

If I can do it, you definitely can too 👊🏽

I get asked all the time about my supplement regime to support my HYROX performance — so here it is!

Race day requires a slightly different approach, but my current daily go-to’s are:

Creatine (I use )
This one is non-negotiable. Creatine is one of the most studied supplements ever and research has consistently shown it helps with muscle repair and supports repeat power efforts — both key for HYROX. I take one 5g scoop daily.

Protein (I use )
I choose whey protein and have 2 scoops daily (60g). This helps me hit ~180–200g per day (around 2g/kg bodyweight), which is key for maintaining lean muscle mass with the amount of running and aerobic work I do along with assisting in recovery.

Beta-Alanine (I use )
Beta-alanine helps buffer H+ ions in the muscle. During high-intensity efforts, H+ builds up and increases acidity. By increasing muscle carnosine levels, beta-alanine helps delay this drop in pH so you can hold higher intensity for longer. In HYROX, where you’re constantly working under fatigue — that can make a big difference. I take one 5g scoop daily.

Hyrox training and performance demands so much from our bodies and even though I work full time and am a new dad I’m doing everything I can to protect my body and perform at my best. Hope this helps you too! 🙌

HYROX Brisbane APAC Regional Race

2nd Place 🥈
Elite 15 ticket to World Champs in Stockholm secured ✔️

This race meant a lot to me and has been in my sights for a while. I knew the qualification spot was possible, but it was never going to come easy. Really proud of the result and left it all out there!

Racing in my home town made it extra special. The support in the arena from family and friends was unreal and genuinely made a massive difference! Big thank you as well to all the Kiwis tuning in from across the ditch, absolute legends 🙏

Massive respect to .james.kelly .s.slee and all the other APAC lads on an epic race! 🚀

Big thank you to my incredible support team and sponsors who made this possible 🙌

Pumped to be representing the Kiwis on the world stage in Stockholm in 10-weeks 🇸🇪 a dream come true!

Let’s get to work 👊🏽
