20K SwimRun
This event on 5 September 2027 combines multiple open water swims in the River Thames with cross country run sections through Wytham Woods. The course comprises three swim legs and three run legs for a total distance of 20K.
Distances include:
- 3.8k swim
- 16.5k run
The swimming sections begin at Eynsham Lock and take place on the River Thames. The running sections follow woodland tracks and cross country terrain in the semi ancient Oxford University woodlands of Wytham. The finish is at Wytham Chalet.
There are three feed stations providing water and isotonic drinks. Any additional nutrition is the responsibility of the participant. Post swim facilities include the Swim Oxford cafe and tent. Race event merchandise is available for sale.
All post swim bags must be loaded at the start at Eynsham Lock. Bags are transported to the chalet and cafe tent in Wytham Woods so participants can change into warm clothes after the event. Changing into warm clothes is mandatory because body temperature can continue to fall after swimming.
There is ample parking at Siemens car park OX29 4BP in Eynsham. Entries are non transferable and participants should review the event refund policy and any event maps for detailed swim and run segments. Visit the organization's website for the most recent information.
