George Nichols

Completed 95 marathons to date, including a marathon in all 50 states and 7 Boston Marathons. George has also finished 7 Ironmans, including Hawaii, and a couple of 50 milers. A former US ranked tennis player, he will have completed a marathon all seven contients when he runs the sister race of the North Pole Marathon - the Antarctic Ice Marathon - in December. The 61-year-old is an orthopaedic surgeon specialising in hip and knee replacements and had his own hip replaced last year. As a result of the new hip he's running slower, but 'just' wants to complete 100 marathons before curtailing his distance running.
