The swim takes place in a man-made lake with calm, shallow clear water and depths around 5–7 ft. The bike course uses quiet country lanes and villages on a fast, flat open-road route that is non-draft legal, well signed, and open to traffic. The run follows grass and gravel trails around the lakes; the surface is flat and spectator-friendly with some technical sections.

All participants must hold a British Triathlon race licence or purchase a single-use Race Pass. On-site camping is available at additional cost. Included for participants are a finishers medal, finishers T-shirt, athlete village, chip-timed results, aid stations, marshals, race photography, bike mechanic support, parking, changing facilities, and medical cover.
