for which he was responsible. He often needed several cars to finish a race. He participated in 5 World Championship Formula One Grands Prix, debuting on 1 July 1956. His best result was a second place at the 1956 British Grand Prix (a shared drive with Peter Collins), and scored a total of four championship points. In 1953 he raced with Chinetti in the Carrera Panamericana. During the 1955 British Grand Prix at Silverstone, Portago was thrown from his Ferrari while racing at 140 km/h after losing control on a patch of oil. He was hospitalized with a broken leg. Bobsleigh He also was a bobsleigh runner, recruiting several cousins in order to form Spain's first bobsleigh team for the 1956 Winter Olympic Games in Cortina d'Ampezzo. He had had only two or three practice runs in Switzerland before buying a pair of sleds. With Portago steering, the two-man bob finished fourth to the surprise of the traditional teams, missing out on a medal by 0.16 seconds. He was introduced to bobsledding by an American from Beloit, Wisconsin, Edmund Nelson, whom he later teamed up with in order to win the Tour de France automobile race. Portago also won a bronze medal in the two-man event at the 1957 FIBT World Championships in St. Moritz. Death He and his co-driver Edmund Nelson were killed on 12 May 1957 in a crash during that year's Mille Miglia, in a straight road section between Cerlongo and Guidizzolo, in the communal territory of Cavriana about 70 km from Brescia, the start and finish point of the event race. The wreck also claimed the lives of nine spectators, among them five children. Portago was apprehensive about competing in the Mille Miglia, a race he considered too dangerous to be run, as he was concerned about the almost complete impossibility about knowing every corner (even with a navigator) and every possible road condition over 1,000 mi (1,600 km) of open public roads with very limited information on what to expect in the race. A tire blew on Portago's third-place Ferrari 335 S causing it to spin into the crowd lining the highway. He was travelling at when the tire went flat. The 335 hurtled over a canal on the left side of the road, then veered back across the canal, causing the deaths of nine onlookers in total. Two of the dead children were hit
