I’m Zebastian Gudmundsson, the coach behind Hyrox Fitness — a project built from over ten years of coaching experience across endurance, strength, and HYROX preparation.

My background includes years of competing in obstacle races, ultramarathons, and HYROX — experiences that have shaped how I understand endurance, recovery, and structure in training.

Hyrox Fitness grew out of a wish to share that approach through clear, well-designed programs and guides. Each plan is grounded in the same principles I apply when working with athletes — practical, measurable, and adaptable to real-life training.

What connects all of it is a belief that training should build both capacity and confidence.

Whether you’re preparing for your next HYROX race or simply want more structure in your weekly training, these resources are designed to help you move with purpose and understanding.

Thanks for being here — I hope these programs bring structure, clarity, and a renewed sense of motivation to your training.
