After 2 1/2 years of HR Zone training and 20# of weight loss, I'm finally able to actually run in my high Z1, Low Z2. Last year most of my run training was redlining Z2 and any sort of incline put me into my Z3 zone.
So the question is... This being my 3rd year of endurance training... Is it more beneficial to keep the same pace at the lower end of Z2 or should I increase pace to again redline the Z2 HR zone? Would having a lower HR on my long runs actually improve my aerobic fat buring capabilities or 8-12 beats doesn't make much of a difference? Meaning aerobic is aerobic no matter how low or high, just as long as it's aerobic.
