AIU bans Joshua Griffiths for three months

The British marathoner's results are disqualified back to 3 May 2026, and Sage Canaday says the case is a strange one.

The Athletics Integrity Unit has banned Great Britain's Joshua Griffiths for three months from 19 June 2026 for presence of a prohibited substance, benzoylecgonine. His results are disqualified from 3 May 2026.

That is the whole of the AIU's post. No explanation of where the sample came from, no statement from the athlete, just the sanction, the window and the link to the case details.

Why the ban is so short

Three months is about as light as an anti-doping sanction gets. It is nothing like the multi-year bans that follow a blood passport case or an EPO positive. Short sanctions of this kind normally attach to substances that are banned in competition rather than to a performance program built over months, and the disqualification of results is tied to a specific date rather than a long stretch of a career.

The sport noticed fast. Sage Canaday, writing about the case, calls it a 2:11 marathoner banned for cocaine in his system, and adds that it is an illegal substance regardless of how it is classified in sport. He also makes an argument you do not hear often, that the drug is not automatically useless to an endurance athlete.

"I will say I see this as a PED that could be abused especially in longer ultras like a Backyard though," Canaday wrote.

Brady Holmer's contribution to the discourse was four words, "I thought it was creatine."

What it actually means

Treat the two reactions as what they are, commentary rather than findings. The AIU has stated the substance, the length and the dates and nothing else. Canaday's line about ultras is his own view of how the drug might be misused, not something the AIU has alleged about Griffiths or about anyone else. Neither post adds a detail about the circumstances of the test.

So the facts available are narrow. A British marathoner is serving a three month ban that started on 19 June 2026, and the results he ran from 3 May 2026 onward are wiped. Everything past that, including the question of whether this was recreational use or anything else, is not in the AIU's statement, and the people posting about it are working from the same short notice everybody else is.
