With gold medals already being won (although not by Britain), the 2012 Olympics are under way very nicely. This second day of sporting action is just as packed as the first with the addition of a few things we haven't seen yet - diving, hockey, canoe slalom, shooting, sailing and water polo. The swimming yesterday was great fun, it looks like there is a little more of that to come today, but not quite as much. There's also plenty more tennis, lots of beach volleyball and some weightlifting as well. Plenty to peruse as the second day gets underway.
