Currently watching an old Mock the Week on Dave, and in the 'stand-up' round one of the topics was the London Olympics. (Or the 'bid' thereby dating the programme somewhat!)

Even I - after my rather pathetic R15 at the weekend - could probably manage that (except of course that it isn't NSE... who is it now? Southern?)!... Nobody would be able to get there. If they do have it in London, they should have a special London Triathalon where you have to get a 133 down Brixton hill to Stockwell, then a Northern Line to London Bridge, and a Network SouthEast back to Croydon. If you can do that in less than six hours, you deserve a gold medal.
