I get up at 7:30am for London rides and sometimes don't get back home until 9pm ish, and that's only because my arms are about to fall off, I'd ride all night if I could.
I've wound myself up a bit about this topic now.
Just click on cleanzine, look at the pictures, read the words, then ask yourself if the problem is with trials or if the problem is with you and then quit being such a whiny bitch and go ride your bike.
