I have a few questions, 1) if he was using a bike, would someone not see him or if he was in a car, would someone not come to run with him and then find him in a car trundling along? I really struggle to see how hes doing either of those but would an expert explanation.
2) Do you think he has three or four runners who have been kept of camera and hes watch muling with them or something? how does watch muling actually work and you manage to keep the data exactly the same, even if you say its wrong? that means then we have a person who he might be muling with who can run like Will and get the same heart rate data, now you lot have two people to go after no?
3) There are so many of you Will C lovers and Goodge deniers, why don't you all club together and pay for Will C to go out there or another of you and watch the last bit. Its Win win, if you prove him to be cheating, you can all become mega famous as the heart rate detectives and get some accolades in some running magazines or forums and feel amazing about yourself and even probably get your money back as well. So I say, all of you club together, get one of you out there and do the last leg, its a no brainer.
You are all so adamant, do something about it rather than sitting on a keyboard and moaning. Take control of the situation and do something
