A classic, reimagined.
For nearly two decades the Dart10k has been the UK's original marathon -distance swim: ten kilometres of wild, road-free river, winding through a stretch of Devon countryside you can only reach by water. Dart10k is the original rite of passage into the marathon swimmers club. It earned its place on every open water swimmer's bucket list for a reason.
For years, the weather threatened it. So we moved the event to July and rebuilt the route. A ferry now carries you upriver to a pontoon launch, starting in cleaner, clearer water. In 2026 we swam the new course for the first time, and it worked.
WHAT'S NEW?
The route
A pontoon start in the Sharpham bends, downriver past Dittisham, finishing at Dart Marina. A better swim from the very first stroke.
WHAT'S BETTER?
The water
A fresh start further downstream in cleaner, clearer water. First, a ferry ride upriver to see the whole course before you swim it.
WHAT'S UNCHANGED?
The soul
The journey, the community, the giddy finish, the deckchairs and the hot chocolate. Still pure Dart.
What the swimmers said.
“A completely brilliant event. I loved every second.”
“Best Dart10k ever.”
“A wonderful new route. What an atmosphere.”
“What a swim.”
Follow the water.

Yes. The start moved further downriver into cleaner, clearer water, reached by a ferry upstream.
Our 2026 swimmers rated it the best Dart10k yet.

A charity place is the only guaranteed way into the Dart10k.
It’s the same swim, and it comes with a £250 fundraising target. That money funds Level Water’s one-to-one swimming lessons for disabled children, so a charity place is the entry we’d most love you to choose.
