A long distance ride more than 100 miles could also be easy if the elevation is low.
I just did a 19 mile mountain bike race over the weekend. Average I was in zone 4 for the 2 hours it took me to complete the race.
Easy or hard is not quantitative. Hard is not an endurance ride. That is where you fail to understand.
Very, very few can do a ZOne 2 ride with an average wattage in Zone 2 over the entire ride that is MORE than 100 miles. I am not saying you cannot, I am saying this is very rare assuming FTP is correct. For a RAAM level rider like you, it is trivial
Average power in Zone 4 for 2 hours is special.
