- The Challenge is restricted to the Intermediate sections at the qualifying events only (OI,AI & CIC sections are not included).
- Points will be awarded to the rider - not the horse.
- Riders can compete at all or a minimum of two qualifying events to be eligible for the final at Highclere Castle, but not necessarily on the same horse.
- Cumulative points will be awarded to the riders coming in the first six places in each qualifying section at each event (12 to the winner; 10 for 2nd place; 8 for 3rd place; 6 for 4th place; 4 for 5th place and 2 for 6th place.) At the final at Highclere Castle double points will be awarded.
- Riders with two or more qualifying entries at any one event will only be allowed to carry forward the points collected on the horse with the highest placing.
- For a horse to qualify for the Final it must be at Intermediate level at the commencement of the Wilton Horse Trials. If a horse is at Advanced level before Wilton all points collected previously will carry forward with the rider who may ride any other Intermediate horse to stay in the Challenge.
- The Final and Prize Giving will be at Highclere Castle on Bank Holiday Monday. In the event of a dead heat the rider finishing the X-C at Highclere nearest to the optimum time will be the winner.
- A first prize of £5,000 will be given by Mitsubishi Motors. Other prizes include a 3 day Novice course of polo lessons at the Tidworth Polo Club; entry tickets and lunch in a private box on Gold Cup day at the Cheltenham Festival; a Gauntlett Sporting clay pigeon shooting day for 4 people; a champagne reception for 12 people at Highclere Castle; a bronze sculpture of a horse given by Style Products; Taittinger champagne and Olympic Horse Feeds supplements.
- The organisers reserve the right to modify the rules if necessary.
