If the Peloton had organized it self to chase Landis all day then they may have been able to limit his gains a bit, but what Landis achieved yesterday was nothing short of amazing and flat out unstoppable. As mentioned, the Peloton doesn't have a lot of aerodynamic advantage in the mountains. Even if they organized and rotated the front group as often seen on the flat stages I don't think it would have worked well in the climbs. Landis proved through out the day that he could ride with someone hanging on to his wheel and he'd just keep going. When the last T-mobile rider fell off Floyd's wheel it was pretty obvious that he had the strength to keep everyone behind him, far behind him.
- still think the peloton was doing just about everything they could. Some of the climbers could have attacked earlier and gone after Landis, but probably would have slowed on the final climb and had all of their efforts for a loss.
