Weird! Just plain weird. I got a non-windy day out in Verdi so I started my run with the hills to my advantage and got a little carried away. I felt faster than normal and my knee felt OK so I got going faster than a normal jog and made it about 1&2/3 mile before cracking and shut it down to finish out three. My first tempo run under 9minutes in years so maybe I gettin' there.
