Fifty years ago I was a club runner, more renowned for club loyalty than glory, though I did run a few good marathons. In 2007, I took up running again because I was alarmed at how unfit I had become. I often train on an elliptical cross-trainer because I have knee and forefoot problems, but I am also working on developing a running style that does not aggravate these problems. I have been strongly influenced by Pirie's book, 'Running Fast and Injury Free' but that book leaves 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 canute1.wordpress.com . I ran a mile race in December 07 and was really chuffed to clock 6:13. Since then various illnesses have added to the ravages of age. Nonethless, I was delighted to complete a 'heptathlon' of events covering a range of activities extending from balance, strength and power to endurance duirng the week following my 70th birthday. fetcheveryone.com/blog/13360/2016/3
