Horner has had a really interesting history. Many consider him the greatest 'wasted talent' that ever straddled a bike. For the majority of his career he lived on bacon hamburgers, beer, cola, candy, you name it. He didn't manage his weight, he didn't adhere to a strict training plan. He just rode his bike damn smart and damn hard up hills. He left the EU racing scene in '99 and returned to the US, where he enjoyed even more beer and 'burgers, because racing here domestically required even less fitness, so his raw talent gave him 'burger margin' to work with. Basically he was a slacker blessed with insane bike skills.
At some point, somebody go through to him and he started watching his diet, training in earnest, and it paid off. He shed a ton of weight, had more energy, and started killing it in races. But by then he was already late 30's, well past his potential prime. But what he has left over still, is pretty damn good.
As for whether he's juiced or not, I have no idea. I'd like to say no, since he's 41 and a doping conviction would burn all his racing for the past 20yrs - no chance for redemption like Valv. Also, the guy just doesn't seem like somebody that id forced to play by anybody else's rules- specifically the EU peloton. There has been a lot written about why he left European racing in '99, and a lot of it centered on him not wanting to dope, and that without doping at that time he had no hope of keeping pace with the peloton.
He's been strong as a bull for the bast 3-4 years... but hasn't gotten the big results either because of horrendous wrecks (Tour concussion where he didn't know where he was at and Bruyneel let him keep riding, or the Giro), or he was a domestique and forced to ride for others.
Whatever the case, the time he put in on Monday was exceptional for anyone. Honestly, I attribute most of it to the pack underestimating Horner. Hell, even if he was doping he shouldn't have been able to put that amount of time into those guys. I suspect the team managers just told them to let him go, figuring he's old and doesn't have the recovery needed for a GT win. We'll see.
