My personal training came to a halt when I herniated my L5/S1 disc in my lower back. The Orthopedist and neurosurgeon both said my long distance running days were over and that I might be able to run a couple of miles slowly as a warm up, but anything more than would be painful.Well, that was numerous 5ks and 10ks, 15half-marathons, 5 marathons, 18 sprint triathlons, 7 olympic triathlons, 6 half Ironman distance triathlons (70.3) and 2 Ironmans ago.This came after extensive research in biomechanics, anatomy and physiology, testing my theories and then applying them. Obviously my formula for reducing the impact on my back worked.I continue to train and run races whenever I can.Due to my success I now coach running and running form privately, for running and triathlon clubs and running stores. I am a USAT Level I Certified Triathlon Coach, a Newton Certified Running Coach, a Lydiard Certified Running Coach and an RRCA Certified Running Coach.
