Cleat placement? How far forward or aft is yours?

As a consequence of a fitting I'm running my cleats full aft on my size 51s. They're no where near as far aft as Steve Hogg's mid foot placement, but, as far aft as the standard slots and screw placement allow. I've not suffered a calf cramp since. It did however impact on my high rpm cadence.

One of the other interesting things I experienced on my return was thigh cramps related to too tight short hems limiting circulation in my legs. I cut the inside bar tacking that attached the ends of the elastic in my shorts and those cramps also disappeared.

Now I'm simply subject to muscular fatigue cramping. Which will probably be best cured by more time on the bike.
