The video above shows a motorist ignoring road restrictions by attempting to drive through a half marathon, and being pushed back by the runners.
The woman, driving a blue Ford Focus, pushes a traffic cone out the way before trying to use the race course as a normal highway.
Eventually, she is brought to a stop as a crowd gathers around her, and a council officer arrives and tells her to stop.
In the video, filmed during Britain's Ocean City Half Marathon in Plymouth, Devon, the woman explains she was driving 'very slowly’.
She said: "I can't get out...listen; I have tried to get out every which way. I have a workshop in Okehampton. I have had no information...I went very slowly."
People around can be heard swearing at the woman - with one runner yelling she could have killed someone.
A council highways official then tells the driver: "Don't move, stay there," to which she replies, "You phone the workshop (to tell them I'll be late)."
Now, a Team GB athlete has taken to Twitter to condemn the woman's actions.
Sprint hurdler David King described it as "disgusting behaviour" and said "you need to watch the video to believe it".
He added: "Why do some people think they are above the law and everyone else?"
