Tom Simpson

Context: Leroux withdrew its sponsorship of the Gitane team for the 1963 season. Simpson was contracted to their manager, Raymond Louviot; Louviot was rejoining Saint-Raphael-Gitane-R. Geminiani and Simpson could follow, but he saw that as a step backwards. Peugeot-BP-Englebert bought the contract from Louviot, which ran until the end of the season. Simpson's season opened with Paris-Nice; he fell out of contention after a series of tyre punctures in the opening stages, using the rest of the race as training. He withdrew from the race on the final stage to rest for his next race, Milan-San Remo; after breaking away by himself he stopped beside the road, which annoyed his fellow riders. At Milan-San Remo, Simpson was in a four-rider breakaway; his tyre punctured, and although he got back to the front, he finished nineteenth. He placed third in the Tour of Flanders in a three-rider sprint. In Paris-Roubaix Simpson worked for teammate, and winner, Emile Daems, finishing ninth. In the one-day Paris-Brussels he was in a breakaway near the Belgian border; with 50 km (31.1 mi) remaining he was left with world road race champion Jean Stablinski of Saint-Raphael-Gitane-R. Geminiani, who attacked on a cobbled climb in Alsemberg outside Brussels. Simpson's bike slipped a gear, and Stablinski stayed away for the victory. After his second-place finish, Simpson led the Super Prestige Pernod International season-long competition for world's best cyclist. The following week he raced in the Ardennes classics, placing thirty-third in Liege-Bastogne-Liege, after he rode alone for about 100 km (62 mi) before being caught in the closing kilometres.  On 26 May, Simpson rode in the one-day, 557 km (346 mi) Bordeaux-Paris. Also known as the "Derby of the Road", it was the longest he had ever ridden. The race began at 1:58 am; the initial 161 km (100 mi) were unpaced until the town of Chatellerault, where dernys (motorised bicycles) paced each rider to the finish. Simpson broke away in a group of three riders. Simpson's pacer, Fernand Wambst, increased his speed, and Simpson dropped the other two. He caught the lead group, thirteen minutes ahead, over a distance of 161 km (100 mi). Simpson attacked, and with 36 km (22.4 mi) remaining, opening a margin of two minutes. His lead steadily increased, and he finished in the Parc des Princes over five minutes ahead of teammate Piet Rentmeester.  Simpson announced that he would not ride the Tour de France, concentrating on the world road championships instead. Before, he won the Isle of Man International in treacherous conditions where only sixteen out of seventy riders finished. At the road world championships in Ronse, Belgium, the Belgians controlled the race until Simpson broke free, catching two riders ahead: Henry Anglade (France) and Seamus Elliott (Ireland). Anglade was dropped, and Elliott refused to work with Simpson. They were caught; the race finished in a bunch sprint, with Simpson crossing the line in 29th. Simpson's season ended with six-day races across Europe and an invitation only race on the Pacific island of New Caledonia, along with other European riders. He skipped his usual winter training schedule for his first skiing holiday at Saint-Gervais-les-Bains in the Alps, taking Helen and his two young daughters, Jane and Joanne. CANNOTANSWER
