The BUPA Great South Run is regarded as one of Europe's leading 10-mile road race and this year takes place on the 26 October.
More than 23,000 runners will be racing over a fast, flat course through Portsmouth, past some of Britain's great naval heritage, allowing for beautiful views of the Isle of Wight.
As well as the 10-mile event on the Sunday, the city also hosts a five kilometre race on Saturday 25 October.
Runners will be hoping for cool, cloudy conditions with a slight breeze. Our Portsmouth weather is the one to check for the conditions on race day.
