Your belated bid for Olympic glory

There's exactly two years to go and Lord Coe is keen that we don't leave our Olympic preparations too late . Coe, who today launches the London organising committee's volunteering programme, said: "This is the right moment to say: 'It's over to you to make of this what you want'. It is shaped by people. I want people to start planning their Games. If you don't volunteer now, you won't volunteer. Don't wait for a year. If you leave it too much later, you won't get a ticket." Cripes! Never mind volunteering and spectating – some of us were thinking we still had time to master a new sport in time to compete at London 2012. If your country needed you, or you just wanted to show off, which event do you reckon you'd have the best chance of picking up from scratch, given 24 months' notice? Which sport have you secretly suspected is not quite as tricky as the others?
