Swim Oxford

A stunning early-morning Lock to Lock 4K swim on the beautiful River Thames, celebrating the very best of open-water swimming in Oxfordshire.

One swimmer described it as:

"A masterful event organised to perfection."

A huge thank you to everyone who makes these events so special—from our safety crews and volunteers to the organisers and supporters behind the scenes. The safety team were outstanding throughout: professional, supportive, friendly, and always there when needed.

The atmosphere, camaraderie, and sense of achievement make these swims truly memorable.

If you've never taken part in one of our events before, we highly recommend giving it a go—you'll love every minute of it.

Thank you to all our swimmers for making it another fantastic day on the river.

Lock to Lock 4K Swim – June 14th 10K August 2nd

For over a decade, swimmers have returned year after year to these truly magical open water events. From the Lock to Lock 4K, to the epic 10K downstream marathon swim, and the brutal 20K SwimRun, these swims inspire dedication, challenge, and unforgettable experiences.

That dedication is matched by the same experienced team and organisers who have supported open water swimmers and swimming events across the UK for many years.

These are not overcrowded mass events — numbers are intentionally very limited, preserving the beauty, grace, and magic of each swim.

From our test results you can clearly see the low levels, way below the recommended excellent 500 cfu’s per 100ml for E-coli and Intestinal Enterococci.

Swimmers unite in morning light,
Immersed in nature’s gleam;
There is no way to miss this call—
A dreaming, swimming dream.

The 10K Marathon Swim in September crosses three locks, with moments to pause before continuing. Many swimmers describe what unfolds as two journeys becoming one — the physical effort and the emotional, internal experience forming together as the swim progresses. What happens between the locks is a space of freedom, awareness, and connection.

We’re here to support the whole journey.
