Harry Jones

About

Harry Jones is a professional trail and ultrarunner from Cardiff, Wales, who has built one of Britain's most decorated international ultra-trail careers across the past decade, all while fuelled entirely by a plant-based diet. He began as a middle-distance track athlete, representing Wales as a junior in the 1500m, and graduated from university with a BSc in Sport Biomedicine and Nutrition before leaving the track scene behind. A move to Thailand in 2013 proved transformative: he discovered trail running in the mountains around Chiang Mai and simultaneously adopted a wholly plant-based diet — a combination that would come to define his public identity as an elite athlete. He began racing internationally in 2017, signed his first professional contract in 2019, and that same year tackled his first 100-mile race at UTMB — finishing 15th among more than 1,400 starters. He has since accumulated nearly 20 podium finishes across UTMB World Series events, made Team GB in 2022, and won the Mozart 11km in Austria that year. He placed 3rd at the Ultra-Trail Snowdonia 50km and 17th at CCC in 2024 — the highest-placed British finisher — and came 7th at UTS 100K in 2026. He competes for the Merrell/Janji team and holds a UTMB Index of 834. Beyond racing, Jones runs the popular Harry Runs YouTube channel and coaches athletes as an accredited run coach, making him one of trail running's most prominent advocates for plant-based performance.
