British and Welsh marathon runner Josh Griffiths has been banned from competition following a positive drug test, the BBC reported on November 11, 2026. Griffiths, who made history as the first British runner to cross the finish line at the 2017 London Marathon, now faces a period of ineligibility under anti-doping regulations.
Details regarding the specific substance detected, the length of the ban, or the governing body that issued the sanction were not disclosed in the initial report. The 2017 London Marathon performance marked a career highlight for Griffiths, who outpaced established British internationals to claim the honor of top British finisher.
