Omer Ahmed, Way In Front of The Bristol Pack
BristolLive reports that Omer believed he had entered for the 10K run. When he had reached the 6th mile he learned that it was a half marathon race so he slowed down a bit and still achieved a personal best for the half marathon.
Later events revealed a mix up about which distance he had entered for and the result was changed. BistolLive used the word "disqualified" in its headline.
