awesome, thank you
last question, which should have been my first. how do you determine Max HR? 220-age gets me 186. but i can be at 180 and not breath heavy? even this past saturday ride, while i was sick, i was around the 175 for a few extend periods but not panting or anything.
also if i go off the 186, 80% would be 150. at 150 is where i do my longer rides, i can do 40miles at 150 with the only limiting factor being my saddle.
