Southampton Running Festival May 2026

Join us for Southampton Running Festival on 31st May 2026

Join us for the return of the Southampton Running Festival. Beginning and ending in the picturesque Southampton Common. It’s the perfect route for a PB featuring woodland, grassland, ponds, wetlands, lakes and parkland in the well used green open space in the centre of the city.

Southampton Common is a designated 'Site of Special Scientific Interest' and an excellent venue for running, walking and watching wildlife.

With RunThrough you can expect a friendly team of marshals to help guide you round the course and cheer you on to the finish, a lively and well-serviced event village with plenty of food and drink options including free goodies from our partners at the finish line after your hard effort.

We have been extensively researching what runners consider important, and sustainability is fast becoming the top issue. Click here to see what RunThrough is doing for sustainability.

You can now grab your Southampton Running Festival event t-shirt for more than 30% off when you buy it as part of your entry on checkout! With the event logo printed on the chest, it’s the perfect keepsake to celebrate your race and wear your achievement with pride!

We can do this with our partner RT Kit as part of a strategic decision to raise awareness about the quality of the product whilst reducing the overall cost of events for those who would prefer not to have a t-shirt included.

Come and enjoy the day with us. Once you enter you will receive a confirmation email. More information will be sent closer to the event.

We can’t wait to see you on the start line!
