A proper sport returns on the 1st of July when the 2006 Tour de France kicks off in Strasbourg. A prologue, 20 stages and 3,600 kilometres later it ends in Paris.
I haven’t a clue who the top contenders are, because the race gets no coverage over here. (It gets no coverage because, allegedly, there’s not enough interest, but there’s not enough interest because there’s no coverage.) However, I have found a Tour de France blog and Le Tour in Google Earth.
