There have already been two great racewalk events at the Olympics, the Men's and Women's 20k walks. Both were exciting races and the "favorites" were upset, especially in the Women's event where local Greek walker Athanasia Tsoumeleka "walked" away with the Gold! The American men had good races, but when you compare them to the field you can see that Europe and Asia (especially China and Russia) put a lot more emphasis on racewalking than we do here in the States.
