More than 15,000 runners will be pounding the streets of Reading this Sunday as the Vitality Half Marathon gets underway.
From elite athletes to enthusiastic amateurs, the runners will take on a 13.1 mile course.
Many participants will be running to raise money for charities and hundreds more are expected to line the streets to urge them on.
As always, residents and visitors are being given forward notice of the large number of road closures on the day.
A series of rolling closures and diversions will be in place at a variety of times, with some starting at 7am and finishing at 3pm.
Roads will be re-opened as soon as runners have passed through and it is safe to do so. Residents and visitors are being asked to plan ahead and allow extra times for their journeys if they need to travel anywhere on the day.
