Come along and cheer on the runners - that's the message from the organisers behind the Pharmalink Maidenhead Half Marathon.
They are encouraging anyone not taking part in the 13.1 mile run to turn up and support those who are.
Entries to the race have already surpassed last year with 2,500 runners warming up for the event on Sunday.
Organiser Claire Donald, of Purple Patch Running, said: "It's the biggest sporting event in Maidenhead and cheering crowds really help the runners rise to the challenge," she said.
"It is something different, a really fun day out for all ages and a great example to our children."
Although pre-registration for the event is now closed entries will still be accepted on the day.
Claire has also suggested a list of 'spectator spots' which will provide the best views of the action. These include Boulters Restaurant and Bar in Boulters Lock Island and The Thames Hotel and Jenners Riverside Cafe in Ray Mead Road.
Runners will set off from the town hall in St Ives Road before racing through Boulters Lock and into Cookham before returning to the High Street.
Temporary road closures will be in effect during the race which starts at 9.30am and is due to finish by 2pm.
Roads impacted include Broadway, Maidenhead Road and Cookham Road.
