In the 2004 Tour de France, Lance Armstrong made history by winning the race for an unprecedented sixth time. In 2005, he became the only 7-time winner and set a new record for the fastest average speed—41.65 kilometers per hour—that stands to this day.

- Ted Williams played for the Boston Red Sox from 1939-1960. Many people credit him with being the greatest hitter of all time. Unfortunately, his career totals are somewhat less impressive than others because his career was interrupted from 1943-1945 by World War II and from 1952-1953 by the Korean War. Some assert that if he had been playing during the war years, he would have broken Hank Aaron’s home run record of 755 and runs batted in (RBI) record of 2297. Below are Williams’ statistics.
