After a break of about three weeks due to a cold I have just completed week4 again and am starting it for a third time. I'm being ultra cautious and keeping a close eye on the twinges I am getting in my thigh muscles. It feels very much like the muscles that worked so hard to protect my hip when it was bad are trying to revert to type. However, with stretching and rolling I am keeping the particularly stubborn muscle under control.
In case anyone is tempted to follow my example, I must emphasise how slowly I run. In fact I run at walking pace following the slow jogging 'niko niko' style advocated in this video. youtube.com/watch?v=9L2b2kh... I am not sure I have fully mastered forefoot landing but I hope that this is minimising the impact on my hip. In any case I find I can enjoy jogging this way and it seems to work for me.
