Did they give the definition of slow?
In the Jack Daniels videos he said easy run should be 60% of max heart rate. Now I assume he means take 60% of the difference between your resting HR and max HR and adding this to your resting? So if you resting is 70 and max is 180, you can 60% of 110 = 66, which you add to the 70 to give 136bpm?
If it was really 60% of max hr, then 60% of 180 is 106bpm, I think I get to that just by getting out of the chair, let alone walking!
Use this to give you an idea............it at least gives you ranges to aim within.

As [MENTION=635]Gary Nelson[/MENTION]'s Teacher implies, lots of us (me included) do far too much running at the 'mediocre' level. It's not in itself a bad thing but it's not an efficient way to improve. Think I've said before, the guy who writes my programme constantly bleats on about running slow runs slower, and fast runs faster. One issue I have is my cadence is high (which follows a transition to a ChiRunning style several years ago) which makes slower running actually uncomfortable - I am desperately trying to 'reduce the gears' and slow down, particularly now as I'm embarking on (hopefully) a new phase of training and will be upping the volume a bit.
