HYROX Running Volume, Sled Pull Tips and Elite 15 Success with Louis Osselaer

In this episode of the Rox Lyfe podcast, we chat with Louis Osselaer. Heading into the 2026 HYROX World Championships, Louis has qualified for the Elite 15 Singles, Elite 15 Doubles, and the Belgium relay team after a series of standout performances.

Louis shares his unusual sporting journey into HYROX, and explains the training changes that have helped him reach the Elite 15 level.

We discuss his approach to running volume, why he's dramatically reduced traditional strength training, and the specific work that's helped him become one of the strongest athletes in the sport on the sled pull and walking lunges.

We also get into:

• Balancing Elite 15 competition with a full-time job

• Building up to 100km running weeks

• His off-season approach and why he takes complete breaks from training

• Solving the digestive issues that were affecting his racing

• Fueling strategies, race nutrition, and recovery

• The mindset shifts that have helped him perform under pressure

• The personal challenges he's overcome away from sport

• His goals for the HYROX World Championships in Stockholm

It was an open, honest conversation packed with practical training insights, performance lessons, and a fascinating look at the life of an Elite 15 athlete balancing world-class competition with a career outside the sport.
