The world’s most beautiful stadium - the entire country of France - annually hosts the most important bike race of the year : the Tour de France. Upwards of 12 million fans line the roads to watch the race. For free. No tickets needed. The race traverses over 2000 miles in 21 days of racing. Every year the route changes, but the mountains are a constant : racers must scale absurdly steep peaks in both the Pyrenees and the Alps before a victory race onto the Champs Elysees in Paris. This year’s tour may be remembered most for the spate of horrible crashes that have eliminated many of the top riders. Most outrageously, a media car hit a cyclist at speed, causing a horrific crash that sent another rider cartwheeling into a barbed-wire fence. Both riders remounted and finished the stage. The race goes on through July 24. — Lane Turner (35 photos total)
