Tougher than most, dumber than the rest. "You can not count the miles until you feel them" TVZ
the Low Heart Rate training group.
I'm running somewhere tomorrow. It's going to be beautiful. I can't wait.
I don't know that you'll NEVER get faster, but the theory is that it's too much unnecessary stress.
A study came out a few months ago, showing that folks with lots of easy mileage and 1-2 speed sessions per week tended to improve in speed more than those doing harder runs. You can poke around for the news item on Runner's World, or if I remember, I'll do it.
Both Hal Higdon and Jack Daniels have a fair amount to say on the topic, also. Hal Higdon has his own website - to get Jack Daniels' words, you'll have to pick up his book on training - VERY worth it.
Life is short, play hard!
