George is a double Paralympic medallist having won silver in paratriathlon and bronze in paracycling at Tokyo 2020. He is also a double European medallist.
His triathlon journey started in 2009 and in 2011 he received classification to compete as a paratriathlete after taking part in a British Triathlon Talent ID Day. Two years later, aged just 17 years old, he finished third in the World Championships in London in his debut season as an elite paratriathlete. He won a second British Championship medal the following year before returning to the podium on a world level in 2015 as he finished second at Buffalo City ITU World Paratriathlon Event before a silver medal in London. He also won his first British Championships that year.
George started the 2016 season with a win in Australia but his only other podium that year came as he won a second British Championship. He also competed in the 2016 Rio Paralympic Games finishing seventh. He started the 2017 season with four straight podium finishes in ITU and ETU events before finishing fourth at the World Championships at the end of the season. His strongest season came in 2018 as he won back-to-back World Paratriathlon Series Events before winning a bronze medal at the World Championship in Australia.
More medals followed in 2019 as he picked up bronze medals in Tokyo and Montreal ahead of the Paralympic Games. He won a gold medal at World Triathlon Para Series Yokohama at the start of 2021 and followed it up with a silver medal at the Tokyo Paralympic Games. He also won a bronze medal in paracycling at the same Games. He then added another four straight medals to his collection as he won again in Yokohama before finishing second in Swansea at the first ever standalone Para Series race in Britain. At the end of 2022 George suffered a grade three diffuse axonal injury in a training ride accident that saw him placed in a coma. He was in a coma for almost eight weeks but in 2023 began swimming, running, and cycling again.
