5:48 mile

I while ago I set the goal (perhaps overly optimistically) of running a 5 minute mile. I hit 5:05 on a treadmill, and in November ran a 5:49 mile on a track. I tried again yesterday and ran a mile on the same track in 5:48. Most of my training recently has been for hills, distance and altitude, and I guess that doesn't necessarily translate into a faster mile.
