Hi all,
I'm looking at changing my HR training from % max to %HRR
I can't seem to find a decent table of what % range I should be targeting for each zone. I have a Garmin where I can set 5 zones manually - any advice on % range for each zone?
Not sure if it's relevant, but I'm training for a 100k so looking to primarily target aerobic fitness on trails with some speed work on track thrown in.
Thank you very much!
