He holds a personal best of 44.48 seconds for the distance set during the semifinals at the 2016 Olympic Games in Rio de Janeiro, where he qualified for the final and finished in 8th place with a time of 44.61.
Hudson-Smith was a gold medallist in the 4×400 metres relay at the 2014 Commonwealth Games, and a gold medallist in the 400 metres at the 2018 European Athletics Championships in Berlin, Germany. He was also a double bronze medallist at the 2013 European Athletics Junior Championships.
Born in Wolverhampton, he joined his local athletics club, Birchfield Harriers, in 2006. He competed in a variety of events before focusing more on the sprints from 2008 onwards. In 2010 and 2011 he mainly concentrated as a 200 metres runner. He was runner-up at the English Schools Championships over that distance in both 2011 and 2012 before finally winning the title in 2013 at the age of eighteen, after returning from a series of hamstring injuries and illness. During 2012 to 2013 he studied on the AASE Apprenticeship at Loughborough College and is now a Physical Education and Sports Coaching student at the University of Worcester, allowing him to continue his education at the same time as training and competing.
