I have been building up my endurance rides, currently 4 hours at 70% of FTP. Makes the 2 x 20 interval sessions seem like fun!
What I'm doing is base (The post above yours). The only things that 4 hours at 70% FTP will get you is fatigued and a severe drop in testosterone. Base training is all about increasing FTP.
What's the difference between 4.5 hours Endurance (your program) and 4 hours at 70% FTP?
