It is run on a flat course through the Stockley Park business campus and along the edges of the adjoining Stockley Pines golf course, and fast times are achievable.
There are trophies for the first three male and female finishers, winners’ medals for veterans and a finisher’s medal for all entrants. The race starts at 10.30am.
