I've been messing around with heart rate training now for some years. This year, I really took the zone 2 training too far and ran nearly all my sessions in the lead-up to a couple of Ironmans and ultras in zone 2. Now, I'm just a really slow runner.
I've tried to find an article that definitively explains what I need to do to get faster and still run long. I have a couple of marathons and ultras to do over the winter. I know everyone says avoid zone 3, so I've been doing that. I am happy to run in zones 4 and 5 for distances of up to 10 miles. But I don't know how to structure my training plan ie what percentage should I be doing zone 2 as opposed to zone 4?
I wish I understood the science behind this. Can anyone help or point me in the direction of something really clear I can read?
Thank you Slowtwitch!
