David enjoys coaching others to help them achieve their potential in health, life, training and racing. Coming from a background of medicine and shift-work, his approach is to fully integrate training into the context of the athletes work, family, and other commitments, optimising overall fitness, nutrition, sleep, and efficient use of time, whilst enjoying the process day-to-day.
