Losing your mojo

what's his base fitness tho?

Not good. The article is called Starting From Scratch and he's struggling to ride 80km! And he's fat.

If you're doing the same small training loop as fast as you can you're not necessarily building much base fitness-I know that I have to force myself to seek out flatter training routes because the roads round here are so hilly that it's impossible to train in particular HR zones for any period of time without getting into the red or hitting descents and dropping to zero rather than building up any base aerobic fitness.

So thrashing yourself everyday you'd get fatigued. You'd end up ill, hating your bike or (hopefully) just riding easier sometimes as well as getting some recovery time.

If I'm fatigued it's not my leg pain that tell me so (they hurt most of the time).
