Eilish McColgan says a school teacher was among those who abused her on social media because of her body shape.
McColgan, who will make her London Marathon debut on Sunday, said that she quickly hit back at the teacher, who also had a daughter, calling her comments a disgrace, before they vanished and the account was suddenly deleted.
With the London Marathon organisation itself taking the decision to come off the social media platform X in protest at some of its unpleasant content, McColgan has suggested that making an account should become subject to mandatory verification.
