Runners will make their way through Whitley, along Shinfield Road, past The Oracle shopping centre, through the town centre, onto the Bath Road before taking on the final leg of the race towards the finishing line at Reading Football Club’s homeground, the Madejski Stadium.
More than 12,000 runners are expected to take part in the hugely popular race, many of them running on behalf of dozens of charity.
The event also includes the GreenPark Challenge – a 3.5 km fun run for all ages, again starting at GreenPark and finishing at the Madejski Stadium, and the Osborne Clarke Business Challenge, which is a relay race run over the Half Marathon course.
There will be some road closures starting at around 7am.
Roads will be closed until the runners have passed through and then reopened. It is hoped the restrictions on all roads will be lifted by 2pm once all the runners have made it to the finishing line.
A full list of closures is available at www.reading.gov.uk or by calling (0118) 937 2771 or (0118) 957 5486. Diversions will be sign posted but drivers are advised to allow extra time for their journey.
Marian Livingston, Lead Councillor for Culture and Sport, said: “The Reading Half Marathon is always a superb sporting and social event, and this year’s event looks set to be the best yet with many more people taking part having been inspired by the Olympics and Paralympics.
“The day promises a great atmosphere amongst the runners and spectators and I hope everyone in Reading will take the opportunity to come and cheer on those taking part.”
All town centre car parks will be open as normal, apart from Oracle Riverside, which will re-open at 11.30am.
People travelling into Reading on the M4 are advised to use junctions 10 and 12 until 1pm to avoid delays.
