Parents are being banned from racing against each other on school sports day because their "over zealous" desire to win is putting them at risk of injury.
No longer content with turning up at the school gates in the latest designer clothes or newest car, it appears competitive mums and dads are now fighting it out in the egg-and-spoon race.
A survey by Country Life magazine found more than two thirds of schools questioned have stopped the once-traditional mothers' and fathers' event. Teachers blamed parents who were going to unhealthy lengths in their determination to be first across the finishing line.
They were concerned that foul play and aggressive behaviour displayed on the field by pushy mums and dads could be a health and safety issue for the school.
Out of the 25 schools polled by Country Life, 17 said they had stopped the mothers and fathers race because of "over zealous" parents. Editor Clive Aslet claimed the genteel era where parents took part in friendly, good-natured races between each other for the entertainment of their children were long gone.
"The only point of parents' races, in those days, was to embarrass the parents," he said.
"Nowadays, some parents have a highly competitive attitude to life and are neurotic about their children succeeding at everything they attempt. It is spoiling the whole thing."
Two schools in the Midlands included in the study said they had reduced the competitive element of their sports day.
John Moreland, assistant head of Rugby School, said: "Our school sports day is one of the numerous inter-house competitions that we hold which helps foster house spirit within a strong school environment." A similar emphasis on competition between teams was found at Malvern College.
The traditional annual school sports day has come under fire in recent years.
Two years ago Maney Hill Primary School in Sutton Coldfield caused controversy when it shunned competitive events in favour of activity-based games to spare less sporty pupils from being 'humiliated'. It has since reversed the policy.
