'hammering' and 'cruising' are just adjectives... instead let's talk about the duration you can be at these HR zones regardless of whether you feel great, crappy, or in between.
if you can ride zone 5 for an hour you have good cardio, muscle endurance fitness and the ability to withstand pain. if you can ride zone 5 for 2 or more hours, your HR max is probably wrong as I noted above... or you're destined for greatness.
