Real Runners don't use threadmills

Went to the gym Sat AM to make up for the past 2 days of rainy weather. Took it easy have to save engery for Sun AM LSD. Saw a warning sign by the gym, saying threadmills are only for warmup purpose. Replacing real running with threadmill will result in worse timings on the track.

Workout summary: 10min Elliptical, 20min Rowing, 20min Cycling.
