Train Heavy, Run Light

As I continue to experiment with ultralight running shoes, I am settling into a routine. I am doing most of my training runs in my older regular weight shoes (Brooks Ghost and occasionally Saucony Ride or Glide). I am saving my new ultra-light shoes for the occasional short run. My theory is that if I overdo the super light weight ones, they will become the new normal and I will get no advantage on race days. It is a version of the hedonics branch of behavioral law and economics which suggest humans adapt to new situations (positive or negative) far more quickly that one would expect. So for the moment, that is my story and I am sticking to it.
