I'm sort of new to all of this. After an almost 40 year lapse, I started riding again two months ago. I ride the same 6 mile route twice each morning and then again each evening. My goal right now is strictly to develop some endurance and strength. I listen to a book-on-tape (well, actually they are on my sdcard in my Galaxy Note 2) and I do not get bored. It's still a training regimen at this point. Soon I will start riding off-road trails and local gravel roads. But for now I'm just pounding it out. With that said, I still love doing it and look forward to it each morning and evening.

BTW, I'm 67 years old and lost 68 pounds since last September. I'm at 221 right now and my target is 170.
