Swimming & running, together.

Swimrun is a sport of alternating swims and runs — you race in your wetsuit the entire time, running out of the water and straight into the next stretch. No transitions, no support crews. Just you, your partner, and the elements.

Invented in the Swedish archipelago in 2002, it has since spread around the globe, building a community of adventurous, welcoming people eager to explore nature outside their comfort zones.

Söuthsea Swimrun has been welcoming people to the sport on England's south coast since 2019 — bringing a sprinkle of Swedish magic to the Solent.
