I've been studying "Chi Running" by Danny Dreyer. It's not so much landing under your centre of gravity as landing when the road is "moving away" from you. This avoids any braking effect. Yes, you will fall forward under the force of gravity, but that is the idea. Then bring your next leg into play to prevent the fall, and carry on ad infinitum. I'm still a beginner at this, but I've managed to change from a heel- to a midfoot-striker, which has made running much more comfortable.
Some help please. I started running about 8 months ago, and have happily built up the distance to 10, occasionally 12, miles. My problem is that after about 3 miles the sole of my feet start to hurt. The best description is that it feels (I imagine) like having my feet beaten with a switch. Not excessively painful, but off-putting. I've tried both inserts in my shoes and rubbing vaseline on before putting on my socks. It helps, but doesn't stop the problem. I'm 64, with a BMI of 25. i contact first with my heel, but put the forefoot down almost immediately, quite hard. Any advice would be welcome. Thanks
