Road closures are to be put in place in Sheffield when the city’s half marathon takes place next month.
Crowds of supporters are expected to line the route of the 13-mile race, happening on Sunday, May 12, and more than 5,400 runners have already signed up.
Athletes will start and finish at Don Valley Stadium, running through the city centre past Ponds Forge before making a turn on Ecclesall Road near Hunters Bar.
Margaret Lilley, chair of the organising committee, said: “We need everyone to be safe, and to cause the least disruption to those not taking part.
“We want to advise motorists of the road closures so they can make alternative plans if travelling across the city on race day.”
Stagecoach Supertram will also run three extra early morning services to help runners take part in the race.
Services will start from the Halfway terminus at 6.12am – nearly two hours earlier than normal on a Sunday.
There will be two other early services, one leaving at 6.23am from Middlewood and one leaving at 7.01am from Meadowhall Interchange.
