20k Swimrun

The 20K Swimrun event, organized by Swim Oxford, takes place in Oxfordshire, UK, featuring a challenging course that combines three swim sections totaling 3.8 km with three running sections covering 16.5 km. The swim segments follow the downstream flow of the River Thames, starting at Eynsham Lock, while the runs traverse scenic, semi-ancient woodlands of Wytham, a site of special scientific interest. The course includes varied terrain with hilly runs and open water swims, offering a brutal yet beautiful experience.

Participants benefit from three feed stations and post-race celebrations at the Swim Oxford Café. The event emphasizes safety with compulsory warm clothing changes after swims. Visit the organization's website for the most recent information.
