So far more than 1,600 people have signed up to the annual Wakefield Hospice 10k.
The 20th annual event, which takes place on Sunday, March 29, starts at 9am from Lawefield Lane, next to Thornes Park, and finishes in Clarence Park.
The route will take runners along Horbury Road and Northfield Lane then onto Southfield Lane and Highfield Road.
Runners will then return along the same route and finish at Clarence Park.
Roads along the route, including Lawefield Lane, Park Avenue and Park Grove Road, will be closed between 8.15am and 11am.
Horbury Road, Northfield Lane and Southfield Lane will be subject to rolling road closures so will be closed for a short period of time.
Event organiser Danielle Cain said: “The important thing to note is that some of the roads are on a rolling road closure so the road is only totally closed for around 45 minutes and then begin to open again.
“Wakefield Hospice apologise for any inconvenience caused by the road closure.
“We consider ourselves very lucky to be granted the road closure order by Wakefield MDC and do everything we can to minimise disruption.
“The road race draws hundreds of people from across Yorkshire to run on the road and we are delighted that this year’s event is set to be the biggest ever.
“Don’t forget anyone can run for funds as we also have the 1k mini run.
“This is perfect as it is the first week of the school holidays and the kids can burn off some energy.”
Entry into the 10k costs £16 or £14 for UK Athletics members. For the second year wheelchair racers can take part in the event.
There is also a 1k mini run which starts on the road and then runs into Thornes Park. The mini run starts at 10.15am and is suitable for all ages and abilities.
