Founder & Head Coach

Gemma Carter

Head of LSB, Running Coach. Full-time running coach for 19 years, working with a wide range of runners from absolute beginners to elite, over distances from short races to ultra running.

BSc in Psychology, specialising in sports psychology. Qualified and worked as a personal trainer in London before founding Carter Coaching and LondonRunningCoach to focus on her area of expertise — particularly trail and long distance. Licensed with UK Athletics, qualified Level 3 personal trainer, and a qualified first aider.

A competitive runner since the age of 11 at regional track level, Gemma ran her first marathon at 19 before progressing into ultras and trail/mountain running — going on to represent her country at the 100km distance and compete internationally. Discovering the trails of Brač while running there led directly to building LSB.
