I have been using a treadmill for timing my 1.5mile runs simply because it allows me to time myself along an exact distance. Appart from the old 1% elevation thing, how would treadmill times generally compare to real running times? I dont have access to a running track or a 1.5mile stretch of level ground (where I live is very hilly). I am running 1.5 miles consistantly a few seconds under 10:00 on the treadmill, any idea if this translates to road running? J.
