A friend of mine who regularly runs long distances was chatting to me last night about his methods. He does 'Chi' running. He looked a bit funny doing it but I 'Youtubed' it this morning and thought I'd look at the principles at least. It's all about aligning your body and leaning forward slightly from the ankle in a sort of 'controlled fall' to work with gravity and propel you forward. Set off for W4 R3 this morning having struggled with the final 5 minutes and found that it worked! I wasn't gasping, I didn't feel like I was lumbering along and I found the whole physicality of the running much easier. I don't know if that was because I was focusing on the action rather than the running! The only thing I did find was that it's hard on my dodgy knee but that may be because I'm a bit stiff with it. I haven't read anything else on here from anyone advocating it so thought I'd ask you all if anyone uses the techniques? I don't want to do myself a mischief but if it makes it easier I'm all for that!
