Ultra/Marathon Coaching

Our online coaching team of three, Ian Sharman, James Elson & Robbie Britton have been designing highly bespoke training programs built around individual athletes, since January 2012. Between us we have the experience of 100's of marathons and ultras across all different types of terrain and environments and we put all of that experience into coaching you to reach your highest potential. Whether you are looking to finish your first ultra or multi-day race, compete at a top level at any ultra distance or simply stay focused and injury free up to your goal event, we can get you there. You can read more about some of the races we have been involved in & our experiences/ coaching qualifications further down the page.
