"Old school doesn't mind repeating the same cycle over and over. They go through running workouts like 10x1000, 3x1.5 mi, 6 mile tempo run for weeks on end before moving on to the next thing."

I must have been coached by an "old school" coach because I have done those runs so many times! I'm sure my coach did the same workouts when he/she was still racing. I now give those workouts to the groups I coach.

Old School is sticking to what works. If it aint broke....
