After lurking these boards for a while, I am now an offical member. Thanks for being such a great resource for training information. Speaking of training, that leads me to my question . . .
I know that zone 1 is for recovery, zone 2 for endurance, and zone 5 is for speed work. I am training for IM CDA this year, and so I will be spending a whole lot of time in zones 1 and 2. What is the purpose of zones 3 and 4?
When training for an IM, is there ever a good reason to go any higher than zone 2 (except for the occasional speed work in zone 5)? Will my training ever take me to zones 3 and 4?
