Most of us run on perceived effort and when racing we're not thinking "pooper, I'm in zone 4.95 I better slow down." All the heart rate stuff is more for the easy days, as Max says to enjoy the birds and flowers and Telletubbies..."
We don't get faster or fitter on the days we crush it. Improvement comes during your rest after the days when you run hard.
Most of this stuff you can find on the internet, but if you're interested there's a seminar near AU this Saturday.
