Surely this is a joke/scam/windup?
As a 75min half marathoner he's half decent, credit where due. To then get that down to around 70mins would be a remarkable achievement but still nowhere near where he needs to be.
If it was possible to get to Beijing from where hes at now then I'd do it myself and i'm already faster than he is.
If he's really set on being at Beijing he'd better start saving up for a ticket.
