But suspensions have hit the underground system’s central line, which serves Stratford station -- the station closest to the Park. Fingers crossed everyone with tickets arrived nice and early.

There is a truly world class line-up for the men’s tennis semfinals, with British No.1 Andy Murray taking on former world No.1 Novak Djokovic. “More!” I hear you cry, well what about 17-time grand slam champion Roger Federer against his 2009 U.S. Open conqueror Juan Martin del Potro? I thought you’d like that.

"With the feverish excitement in the Olympic Park, it’s easy to forget that the Games are continuing along the length and breadth of Britain. In just under 30 minutes time, way up north in Newcastle, the U.S. women’s football team go for a place in the semifinals against New Zealand. Soccer’s grand tour of the British Isles continues with the ever-impressive Brazil facing off against world champions Japan, before the hosts Great Britain try to book a place in the last four against Canada in Coventry. One country has already booked its place in the medal matches, with France registering a 2-1 win over Sweden earlier today."
