2010 is the centenary of the introduction of the Pyrenees into the Tour de France route. It was a contentious decision at that time to send riders on their primitive bicycles into the high mountains. How Tour organiser Henri Desgrange was tricked by his assistant, Georges Steines, into agreeing to direct his riders over 2,000-metre cols is one of the great legends of Tour history. The 1910 race was won by the French champion Octave Lapize, who added to the controversy on the top of the Col du Tourmalet by shouting out to the Tour officials, 'Vous etes des assassins! Oui, des assassins!' - 'You are murderers! Yes, murderers!' For Lapize himself, this was his only Tour victory, but he was an outstanding one-day classics rider and also a fine track cyclist, winning a bronze medal at the 1908 Olympics. During the First World War Lapize, a fighter pilot in the French army, was shot down in June, 1917, and died in a hospital the following month. For all his initial misgivings, Desgrange had no hesitation in calling the Pyrenean venture a great success and those high cols immediately became an indispensable part of any Tour route. In the 100 years since Octave Lapize's first epic ascent the Tourmalet has figured 73 times. Author, Jean Bobet, writes: In the early 1950s, my brother Louison and I were living in the Eastern suburbs of Paris. Each time we went training, we would cycle past the Cafe Lapize in Villiers-sur-Marne. This Lapize seemed to follow us everywhere. At the time, Lapize toe straps were the only ones on the market. At the Montlhery motor racing circuit there was the famous slope known as the Cote Lapize, which determined the outcome of every race held there. Back in Villiers-sur-Marne, you couldn't find Octave Lapize at the cafe any more. We knew he had been killed in the war, the 1914-18 one. People even said he died a hero. The Cafe Lapize belonged to the champion's father. One day, I ducked under the arbour at the entrance and went inside. Across the large room, I came face to face with the great Octave Lapize, in a large pastel drawing on the wall, resplendent in his French champion's tricolour jersey. I was looking at the portrait of a true aristocrat. An inscription underneath read "Winner of the Tour de France, Paris-Roubaix (three times), Paris-Brussels (three times).' I spent fifty years thinking about Octave Lapize. Then, one day, I decided to follow his tracks and tell his story. Thanks to him, I experienced the golden age of cycling at the beginning of the twentieth century. The Lapize years.

"Tomorrow we ride. that's what my brother Louison and I used to say as we arranged to meet: every day while we were racing cyclists, and then just on Sundays when we weren't competing any more. We kept on riding until the end of his life, because even then - especially then, perhaps - we always understood each other best on bikes. We had always needed a bike beneath us. In the words of the song, we took the high road and the low road: in cycling, the glory days always have less glorious ones on their tail. Thanks to Louison, I had the good fortune to ride with him through the golden years, the 50s: the years of post-war reconstruction, of Coppi and Bartali, of Kubler and Koblet, of Gaul and Van Steenbergen, Anquetil and Darrigade. These are names that speak of the aristocracy of cycling, and the fierceness of the competition. Every day, Louison and I took pleasure in cycling together, whether on our intimate journeys through Brittany or the Alps, or in the frenzy of the Tour de France or Giro d'Italia." Jean Bobet. Jean Bobet's book is not so much a biography of his superstar brother Louison, nor his own autobiography, but rather an account of the intermingling of their two lives. And what lives - Louison, triple Tour de France winner and World Champion and Jean (no mean rider himself) who gave up an academic career to ride in the service of his brother in pursuit of sporting glory. Set in the period after the war, this story brings alive the romance of the great races and the star riders of the day whose exploits lifted the public spirit after years of conflict and economic hardship.
