He says - "Like I have been saying all along however, is it is just another race, it is still 26.2 miles and I have to treat it like that. The preparation, the training, and everything else has been geared towards running a marathon, and at the end of the day that is what I have to do. It just happens to be the Olympic Marathon."
We say - Scott will do well to get on the podium with runners from Ethiopia and Kenya looking very strong, but with the home crowd behind him, who knows.
