He was always going to struggle at the end of a season. Most of the guys he's riding against have had fulls season's so are pretty much race fit, whereas Brad has had to only do training. They say that the only real prep for racing is to race, which is why some of the early season races like Paris-Nice, Dauphine, Trentino etc...are used heavily to get into shape for the Grand Tours. If you've missed most of the yr then it's going to be really hard to play catch up. Brad has only really raced in the Giro this yr with maybe a few smaller stage races thrown in, probably not enough miles competitively to really count.
