I started running over 7 decades ago as a five year old, running to and from school. Fifty years ago, I was a club runner, more renowned for club loyalty than glory, though I did run a few good marathons. In subsequent years my love of the outdoors led me to spend more time on the hills and mountains, in Australia, the UK and in the Alps. Twenty five years ago I returned to trail running in the forests of Canada. In the midst of the wave of enthusiasm for a better understanding of the mechanics of efficient running I joined Fetch in 2007. I had been strongly influenced by Pirie's book, 'Running Fast and Injury Free' but that book left many questions unanswered, and unfortunately, Pirie is now dead. I learned a lot from the Fetch Efficient Running Style thread and have augmented Pirie's ideas with ideas from Pose, Stride Mechanics and Chi. As I have constructed this synthesis of ideas, I have posted it on my blog at http://canute1.wordpress.com/. I ran a mile race in December 07 and was really chuffed to clock 6:13, though that was quite a lot slower than my marathon pace in my heyday. Since then various illnesses have added to the ravages of age. Nonetheless, I was delighted to complete a 'heptathlon' of events covering a range of activities extending from balance, strength and power to endurance during the week following my 70th birthday. fetcheveryone.com/blog/13360/2016/3
