@millarmind: I think @MarkCavendish needs a hug from the nation. Normally he's angry when he loses, today he was just sad. He feels like he let GB down.
@millarmind: On the bright side it was the most amazing feeling in the world carrying the weight of a nation. Feel terrible we didn't deliver.
@millarmind: We've never experienced anything like today, it was magical, and will be imprinted in our memories. Thank you everybody for the support.
@davidcarry: Wow! Just achieved my ultimate dream.. Making the Olympic final at my home Olympics. Thank you to everyone who's helped and supported me.

@davidcarry: I promised myself, if I made the Olympic final, i'd get a @rocketespressou machine. Now to choose which one! Any advice?
