Participants run through the semi-ancient woodlands of Wytham Wood, a site of special scientific interest, covering distances of 7.6K, 1.5K, and 8K. The swim sections, ranging from 1K to 1.6K, take place downstream along the River Thames.

The course is known for its hilly terrain and beautiful open water swims, offering a brutal yet rewarding experience.
