In Zone 5, lactic acid builds up quickly, so this intensity can not be sustained for long periods, but is useful for sustained surges

aerobic with 2 days
of «speed») the following week my
energy levels were back to normal... not sure I do so well in ketogenic state or perhaps I wasn't as balanced as I should have been (carb, protein, fat) or my body just isn't acclimitized to those things yet (ketosis)... working on it though...

of the
aerobic spectrum and any surges into the anaerobic spectrum
of metabolism.
