Dart 10k

The first, and arguably finest, 10k swim out there!

Jess Rose

3rd – 4th September 2022

We are delighted to announce that after a few years absence from our summers, the Dart10k 2022 is going ahead! This iconic event is now run by a new event team Swim Collective from Level Water. It remains supported by, and supporting, The Outdoor Swimming Society and we look forward to seeing you there.


The Dart 10k was the first, and is arguably the finest, 10k swim on the open water calendar, growing from 200 to 1600 swimmers a year over ten years. The course of the Dart 10K is a unique journey punctuated by landmarks such as the Cormorant Tree, the white rock, Sharpham boathouse and Bow Creek. It’s supported by volunteers from the local and swimming community, who make it one of the most special events in the swimming calendar. It’s a journey, not a race – there are fast swimmers, skins swimmers, swimming families (everyone 16 and over is welcome), disabled swimmers, newbies, butterfly swimmers, leisurely swimmers – whatever the level, there’s room for everyone in the river.

Find out more about the event in the 2019 event report and gallery.

Everyone is welcome, and very much encouraged, to join the swim. Swimmers aged 16 and 17 are welcome, but will need their parent or guardian to provide parental consent prior to the swim. 

The swim is assisted by river flow, but swimmers should still train to swim 10km. All swimmers will need to be acclimatised to outdoor swim temperatures by the day, and to have experience of chop and open water. 


All information about the 2022 events will be shared through the Swim Collective, and we will also keep OSS members informed through elsewhere and our social media channels. We look forward to seeing you there!
