HYROX and the Clean vs Dirty Fuel Mindset with Kat Parnell

In this episode of the Rox Lyfe podcast, we chat with Kat Parnell.

Kat has enjoyed a breakthrough HYROX season, making multiple Elite 15 appearances and qualifying for the 2026 HYROX World Championships in doubles alongside her long-time friend and racing partner Jade Skillen. But this conversation goes far beyond race results.

We discuss the training and mindset changes that helped Kat reach a new level of performance, why she realised she had been overtraining and under-fuelling for years, and how working with a coach has transformed her approach to both training and recovery.

We also get into:

• The concept of "clean fuel" versus "dirty fuel"

• Why self-worth and performance are often linked in unhealthy ways

• Recovering from an ACL rupture suffered moments after qualifying in Warsaw

• What makes her doubles partnership with Jade so effective

• Carrying the Olympic torch and appearing on Ninja Warrior

• Learning to enjoy the process rather than chasing validation

It’s an honest, thoughtful conversation about performance, identity, mindset, and finding a healthier relationship with sport.
