About Lawrence Cronk

Lawrence is an endurance coach who loves helping athletes discover what they’re capable of. His sporting journey started with cricket—representing Wales at youth level and joining the MCC Universities Centre of Excellence in Cardiff—where a fitness test sparked a lifelong fascination with performance.

After a stint in finance, he moved into the fitness industry as a personal trainer, then progressed to gym management, athlete testing, swim coaching, and ultimately full-time endurance coaching. Along the way he kept competing across swim, bike, and run. Lawrence now lives in Slovenia and coaches athletes in the UK, Europe, Australia, the USA, and the Middle East.
