Tongue in cheek, yes? Seriously, you or I could go to the Games and "coach" Farah to gold - in the 10K at least. It will probably be a relatively slow first 5K (or even more if it's hot and humid) and there's nobody beats Farah in that kind of race. The 5K looks more difficult but unless it's a very fast paced effort from the gun I still don't see anyone topping Farah over the last 600m or so.
Could it even be an advantage to have run the 10K prior to the 5K (assuming it went well) rather than hanging around till the back end of the programme to compete? Recovery isn't that much of an issue; remember, Ron Clarke always said the faster you run, the fitter you obviously are so the quicker you recover!
