Earlier this week, at the Queen Elizabeth II Conference Centre, the mayor of London unveiled the route for the 2007 Tour de France. That’s no misprint. What the French call la Grande Boucle, the pride of Gaul, will spend its first three days in perfidious Albion, opening at Trafalgar Square. The prologue time trial, a day later, will send the caravan of gaudy advertising floats, mad photojournalists atop motor scooters, cars stuffed with VIPs, even a couple hundred bicycle racers wedged in between, past Big Ben, Westminster Abbey and Buckingham Palace. And then the first stage of the race begins on the Mall and finishes up, 125 miles later, in Canterbury, before crossing back to the Continent.London won the right to give the 103-year-old bicycle race a distinctly English flavor with a £1.5 billion bid to the organizers, setting off Tour de l’Angleterre fever, of a sort, and for good reason. A London-to-Paris race, from The Mall to the Champs-Elysées, will link the greatest of Europe’s capitals for the first time. “When the Grand Départ gets here next summer, it will receive the biggest welcome from the fastest growing cycling city in Europe,” Mayor Ken Livingstone said in unveiling the itinerary Thursday.
