With its flat, fast 10-mile route, incredible atmosphere and coastal views to die for, it’s easy to see why the Great South Run is one of our top runner-recommended events.
Plus, there’s also the Great South 5K and Junior & Mini races – so whether you’re chasing a new PB or cheering on your little ones, there really is something for everyone.
On the fence? Here’s why Portsmouth might just be your new favourite start line.
Why we love Portsmouth (and you will too)
Portsmouth knows how to put on a show. And why wouldn’t it? It’s got a cracking coastline, naval history and more personality than Will Ferrell (Portsmouth FC’s most famous fan, FYI). From the historic dockyards to its buzzing Southsea seafront, Portsmouth gives you plenty to see, do and experience – with a dose of sea breeze for good measure.
Plus, the Great South Run crowd is loud, proud and guaranteed to carry you through the final stretch – even if your legs are screaming at you to stop.
Must-Run Routes
Southsea Seafront. Total no-brainer: stunning scenery, flat terrain and endless fresh air. The Great South Run finishes here, and we challenge you *not* to have a Chariots of Fire moment.
Clarence Esplanade to Eastney (and back). The perfect uninterrupted four miler (out-and-back). No hills, no traffic – just you, the views and an ice cream van (or two).
Old Portsmouth and the Historic Dockyards. Like your runs wriggly? A run through old Portsmouth and the historic dockyards will see you winding through cobbled streets, and past centuries-old pubs. HMS Victory is a must-see (and also features on the Great South Run route).
Southsea Common. Home to a weekly Parkrun, this green space is a favourite with runners, dog walkers and families. It’s perfect for intervals, outdoor circuits or a simple, gentle jog.

Find your (running) tribe
Look out for local groups like Portsmouth Joggers (“Running around Pompey since 1976”), Baffins Fit Club (“Run often, run long but never outrun your joy of running”) and Isle of Wight Road Runners (“A Club For All”). They know all the best routes and won’t bat an eyelid if you turn up in mismatched kit. More friendly Portsmouth running clubs here.
When in Portsmouth…
Brunch and coffee goals. Head to Southsea Coffee Co for strong coffee and legendary banana bread, or try award-winning indie The Garage Lounge for brunch heaven. Something sweet? The Tenth Hole is Actual Cake Heaven.
Treat yourself. Pay a visit to Alexandra Sports, Portsmouth’s best-known running shop for 40+ years. They’ve got super staff, excellent stock and pride themselves on excellent customer service (“We’re old-fashioned”).
Fun and free. Wave at the ships on the Historic Dockyards, walk the old city walls or take your medal for a stroll along the beach. Chips aren’t free sadly, but the salty air is.
Portsmouth delivers big event day energy, a route as flat as a pancake and a proper coastal buzz. Ready to see what the fuss is about? Check out the Great South Run, 5K, and Junior & Mini events here.
