About Coach James Sieber
I come from a background in downhill ski racing, competing for England, and working as an instructor and race coach for nearly 10 years. After retiring from ski racing, I transitioned into powerlifting, setting multiple regional and national records. After moving to Australia and living a less active lifestyle for a few years, I returned to strength training and embraced road and trail running.

As of December 2024, I work full-time as an online running and strength coach. This allows me to provide the communication, accountability, and support that every athlete deserves. I help athletes progress toward their goals and discover their potential in a way that fits their unique lifestyles.

Who I Work With
Whether you’re a new or returning runner focused on road or trail running, from 5k to marathon, sub-ultra, or 100mile, chasing podium finishes, or simply aiming to run stronger, all I ask is that you’re committed to your goals and willing to put in the work. In return, I’ll apply over a decade of coaching experience and training expertise to help you unlock your full potential and enjoy the process.
