The race starts from the historic grounds of Berkhamsted Castle and finishes in Wendover. The opening section includes an undulating 10K through the Ashridge Estate. The route from Ivinghoe Beacon toward Aldbury is noted on the event as a standout 5K of the Ridgeway. Organisers note the current course measures around 51 km due to HS2 related diversions near Wendover.
