- 27-year-old is a part of the British four-man team with eyes on medals in Italy
- Gulliver tested positive for banned substance ostarine – as CJ Ujah did in Tokyo
- Gulliver won 2023 European gold, as well as 2025 world championship bronze
Leading British bobsledder Arran Gulliver has failed a drugs test, casting his participation at next year’s Winter Olympics into major doubt.
The 27-year-old, a key part of the four-man bobsleigh team that has been tipped for a medal at the Games in Italy, was positive for ostarine – the same banned substance found in CJ Ujah after the Tokyo Olympics in 2021, causing the men’s 4x100m relay squad to be stripped of their silver medals.
The substance, which can enhance muscle growth, was discovered in out-of-competition testing on March 2. It has not yet been confirmed if Gulliver has requested a test on his B sample, with the possibility of a two-year ban hanging over his head. Ujah was eventually given a 22-month backdated ban after authorities accepted he did not intentionally take drugs.
The British Olympic Association declined to comment, though it will be a significant blow for Team GB. Gulliver has been a regular part of Brad Hall’s four-man crew which won European gold in 2023, as well as world championship silver and bronze medals in 2023 and 2025 respectively.
The International Testing Agency, who are prosecuting the case, confirmed Gulliver has been handed a provisional suspension.
Gulliver was also part of Hall’s quad when they won Britain won gold at the IBSF World Cup in Winterberg, Germany in January. British Bobsleigh and Skeleton have been contacted for comment.
