ROAD closures for the Gloucester 10K race left some city centre residents struggling to get about.
The race, held last Sunday, saw a number of routes shut for several hours for the runners to pass through.
But one resident, who runs a care providing firm, said: "We work with a lot of vulnerable people in the city centre and they expect our girls to be there for them.
"I support the idea of the race but it shouldn't be in the city centre. Why don't they do it in the countryside where it isn't going to affect people?"
A Gloucester Docks resident told users of Thisisgloucestershire.co.uk that he arrived to work an hour late after not being allowed to leave the area.
Another resident said: "I suggest before they organise another race, the route does not shut off a whole community. The Pied Piper race is much larger but we do not have this hassle."
Amy Budd, marketing manager for race organisers GO2, said: "We're sorry that some residents were affected by the road closures.
"Making a race traffic-free always causes some disruption, but we worked hard to keep it to a minimum."
She added that closures were advertised in the media, through leaflets and road signs. All roads reopened by 10.55am.
Plans are now afoot for next year's race.
Organisers said they want to double the number of people taking part. This year they had 611 runners.
They will announce the date later this year but have said it will be around the same time.
