From Couch to Ironman at 48

What happens when someone with zero athletic background decides to completely change their life… and accidentally signs up for an Ironman four months later?

In this episode of the Triathlon Nutrition Academy Podcast, Advanced Sports Dietitian Taryn Richardson sits down with Triathlon Nutrition Academy athlete Chris Tubbs to unpack his incredible journey from couch potato to multiple Ironman finisher.

Chris started triathlon at 48 years old, while travelling 60% of the time for work in the biotech industry. Early on, things didn’t go to plan. Despite doing the training, races were ending in DNFs, cramping, nausea and serious frustration.

The surprising part? Fitness wasn’t the problem.

Through this conversation, Chris shares how dialling in his nutrition and hydration completely changed his ability to train, race and actually finish events. From ditching an expensive supplement habit to discovering he loses more than 2 litres of sweat per hour, this episode highlights just how powerful personalised nutrition can be for endurance performance.

It’s an honest, inspiring conversation about resilience, learning from mistakes and why it’s never too late to start something big.

In This Episode We Discuss

The moment that sparked his decision to completely change his lifestyle
Accidentally signing up for an Ironman just four months into triathlon
Why he kept experiencing DNFs, cramping and poor race performances

How he saved hundreds of dollars a month by ditching unnecessary supplements

Why hydration, not carbs, was the missing piece of his race-day puzzle
The challenges of fuelling properly while travelling constantly for work

Chris is proof that when you stop guessing and start fuelling strategically, everything changes.
