Bike fit / correct riding position

As a duathlete with a nigglesome knee - and previously achilles problem but that's cleared up now - I'm finding this very interesting and worthy of experimentation. (I'm thinking of the non-drastic-shoe-modification strategy of "method 2".) Will be very interested to see how you get on with the midfoot strategy.

I'm hoping less pain and more power will be the result. If it actually works it'll be great!
