Residents and businesses on and around the route for the first Plusnet Yorkshire Marathon in York and surrounding areas are being warned of planned road closures.
To ensure the safe passage of an expected 6,500 runners there will be disruption to the road network over the weekend of October 19-20.
Thousands of leaflets are being distributed to homes and businesses along the 26.2-mile route advising them of the planned closures.
The marathon starts and finishes at the University of York’s Heslington campus.
Its route travels through the city centre and takes runners north eastwards out of the city and through, or close to, Stockton on the Forest, Grange Wood, Upper Helmsley, Stamford Bridge, Gate Helmsley, Turkers Wood, Murton, Osbaldwick and back towards Heslington.
To allow an “event village” to be set up, University Road, York, will be closed between Innovation Way and Green Dykes Lane on the Saturday from noon until 9pm on the Sunday.
Road closures affecting highways around the marathon’s route on the Sunday will begin from 6am. Roads will reopen on a rolling basis when it is safe to do so.
City centre roads affected by the closures include: Walmgate, Hope Street, Leadmill Lane, Piccadilly, Parliament Street, Blake Street, Duncombe Place, Deangate, Goodramgate and Monkgate. Most will close from around 9.15am and should reopen by around 10.30am.

Event leader Lynne Preston said: “To ensure the safety of our participants and spectators, some road closures will necessary.
“We would like to apologise in advance for any inconvenience caused.”
