"How hard can it be?" Training Update

[Grog]

My knees are feeling great - ever since I had my bike fit and stopped overextending them every day.

Oops I had misread what you wrote above.

If you don't have pain, I'd give the shoes a chance, but when light pain arises in any joint (ankles, knees, hips) - or at about 200 miles - I'd retire them to walking-shoe status...

It's also not a bad idea to have two pairs of shoes and to alternate, especially if you're going to be running two days in a row once in a while. I learned that the hard way. Running every day breaks shoes down much faster, it seems.
