could be a number of things.......
maybe it is partly due to a lack of confidence brought on through not feeling 100%, he got spat out the back on the first serious climb(stage7 if i remember correctly.) and admitted he had to slow down due to being on the limit, as well as suffering in the heat. although he was positive 3 days before on the cobblse(stage3) after finishing 8th.
maybe he realised that much harder was round the corner and it dawned on him that he is gonna struggle. ???????????
sportsmen of all kinds suffer with "head injuries" when things aren't just right.......was it petecchi(sp) that said to cav...."it aint in your legs mate, its in your head".....look at cav at the start of the tour after a crash and a sprint falure, one good proformance picked him up and put him back on that cloud as cav puts it.
maybe brad kinda threw in the towel...........maybe something that simple.
