Guillaume Martin has joined fellow French rider Romain Bardet’s call to ban the use of ketones, suggesting the use of the dietary supplement and energy source by some riders and teams is creating unfairness in the peloton.

Thibaut Pinot, Arnaud Demare and Bardet have all recently raised questions about the use of ketones and highlighted the difference in results they could lead to. A number of leading teams, including Jumbo-Visma and Trek-Segafredo have admitted to using ketones, with a number of others said to have ordered them in quantity for major objectives such as the Tour de France.
