Last Christmas Wham!

A unique athletics event is happening today, a triathlon that's taking place in France, Belgium and here in London.
Around a hundred people have already completed a 15 hundred metre swim in Paris, next it's a 40 kilometre bike ride in Brussels, then a trip to London to round it off with a 10k run in Regents Park.
They're travelling by train between the venues and it's all to celebrate Eurostar's partnership with London 2012.
