Testathlon Lyon 2026

Testathlon Lyon is a charity running event in Parc de Parilly, Lyon, held in November to raise money for research into Inflammatory Bowel Diseases, including Crohn's disease and ulcerative colitis. It is built around timed trail races of 7 km, 14 km, and 21 km, with a 5 km walk for people who prefer a non-racing option and a free 1 km race for children. About 1,500 people join each year, so it feels like a local community race with a clear medical cause rather than a large commercial event. The Lyon branch of the DigestScience Foundation organizes it with the hepatogastroenterology department at Lyon Sud hospital, which gives the fundraising a direct link to doctors and researchers working on these diseases. The cause is not abstract: IBD affects about 300,000 people in France, with about 8,000 new cases each year.
