Aside from the main event, there will be other distances people can run along, including a half-marathon, 10k, 5k and a Fun Run.
All distances will start and finish at Guildhall Square, with the routes taking runners past landmarks like Itchen Bridge and St Mary’s Stadium.
If you’re taking part on the day, you might want to give the route map a look just to have an idea of how you’ll be going around the city.
What is the route map for the 2025 Southampton Marathon?
According to the event website, the full marathon route begins in Guildhall Square, where you’ll run past the ABP Southampton docks.
After that, you’ll go over Itchen Bridge, which offers “glorious views across the Southampton Waters, The Solent and, even, the New Forest”.
It adds: “Following a section by the shoreline at Weston Shore, the route takes you inside the legendary St Mary’s Football Stadium, home to Southampton Football Club (aka The Saints!).
“Passing over Northam Bridge with riverside views once again, you will run through the beautiful Riverside Park before crossing into Portswood and running through Southampton Common (home to the UK’s second largest parkrun!).”
From here, you’ll then repeat a second lap of the course to make it a full marathon.
An interactive map of the route can be found on the website here.
What is the 10k and 5k route map?
The 10k and 5k route maps are slightly different and can be viewed on the website here and here.
For those on the 10k route, you’ll go through Queen’s Park, over the Itchen Bridge and then complete a loop of Woolston.
After that, you’ll head back to the city centre, past St Mary’s Stadium, before running around many of the city’s green spaces.

You’ll conclude with a short distance along Above Bar Street.
Meanwhile, the 5k route will take you through Queens Park but will avoid going over the Itchen Bridge and doing the Woolston loop.
With St Mary’s Stadium in your sight, you’ll then turn up towards Solent University and some of the city’s green spaces before getting to the finish.
