The race has a three hour cutoff. It is fully marshalled and includes water stations on the route. Free parking and park entry are included for the runner and family members. Finishers receive a medal, water and a banana. Trophies are awarded to the first, second and third placed male and female finishers.

A small race village will host stalls and there will be spot prizes. The confirmed route will be published nearer the event. The organiser is Worksop Harriers Athletic Club. Visit the organization's website for the most recent information.
