A Doncaster town centre 5K race has been moved after organisers said they 'cannot guarantee' the safety of runners.
The annual race, which draws hundreds of participants each year, clashes with England playing in a potential World Cup semi-final on Wednesday, July 11, if they progress against Sweden on Saturday.
Organisers said due to previous 'serious disorder' in the town centre when England are playing, they decided to move the race to the following week at 7pm.
Doncaster Council has managed to keep all the proposed road closures for the following week after discussions with organisers.
Kevin Lincoln, race director, said: "It is with regret that our town centre races on the July 11 has had to be cancelled due to a clash with the World Cup semi-final football match.
"There has been serious disorder in the town centre following recent World Cup matches and we cannot guarantee safety.
"The last time England played, the streets were filled with people and some even were seen on top of bus shelters. The roads we're proposing to close, it would just be a nightmare.
"It's too big a risk to take from a safety perspective so we think it's for the best."
Runners with race entries are still valid for the July 18 date. Those who cannot make the new date can be entered into next year's race for no extra fee.
