American Chris Horner will not only become the first American to win the demanding Vuelta a Espana, but even more impressively he will be the oldest ever rider to ever win one of cycling's three grand tours at 41 years of age, when the race finishes in Madrid today. This is an incredible achievement from a man right at the end of his career, in probably the most demanding sport on the planet. His three weeks in the race and battling much younger riders who are at the peak of their powers has been epic to watch.
