Sam Holness

Sam is an inspirational endurance athlete driving diversity and redefining what people perceive possible with Autism Spectrum Disorder (ASD). In 2022, he became the first openly Autistic endurance athlete to complete the Ironman World Championships in Kona, Hawaii, showing it is possible to break through the perceived societal barriers of sport.


About Sam Holness

On a global stage, Sam is challenging the stereotypes for those with neurodiversity, while tackling one of the world’s toughest endurance sports.

In 2024, Sam will be continuing to prove there are no limitations to athletes with neurodiversity through competing in more Ironman Triathlon events, Marathons, Cycling and Trail Running events. Sam is coached by his father, Tony Holness, and they have delivered speeches together for corporates including KPMG, Lloyds Bank, Havas and more, as well as for schools, universities and
local community groups.
