The swim takes place in the man-made lake at Allerthorpe Lakeland Park with calm, clear water and depths of about 5–7 ft; starts use small waves and sheltered conditions. The bike course is a fast, flat open-road route through quiet country lanes and villages, non-draft legal, well signed, and open to traffic. The run follows grass and gravel trails around the lakes and is described as flat, scenic, and spectator-friendly.

All participants must hold a British Triathlon race licence, either an annual Core or Ultimate membership or a single-use Race Pass (£8). Included for athletes are a finishers medal and T-shirt, chip timing, way-marked and marshalled routes, aid stations, on-site parking, changing facilities, medical support, and complimentary finishers drink. Camping is available on site at an additional cost; book directly with the venue. Visit the organization's website for the most recent information.
