MORE than 500 riders will compete at the Autumn Gatcombe Novice, Intermediate and International CIC** Event, which takes place this Saturday and Sunday.

This year's event will be sponsored by the United Arab Emirates Equestrian & Racing Federation.

The entry is headed by the British Olympic Gold Medallist Leslie Law, competing in the CIC** on the Sunday.

There will also be representatives from 12 overseas countries giving a truly international flavour to this popular Gloucestershire event.

Starting at 9.00am on both days, the event will feature the dressage, show jumping and cross-country phases running throughout both days.

At various times during both days, HRH The Princess Royal will present prizes to the winners of each of the various sections on both days.

The event also boasts a new associate sponsor Countax Garden Tractors who will be sponsoring the finale to the event on Sunday. This will take the form of an arena knockout sprint competition using Countax Williams WF1-600H garden tractors, which has just been launched on the UK market, driven by 16 eventing personalities.

Celebrating the eleventh year of running, the event takes place on a course designed by HRH the Princess Royal and her event organiser Pattie Foden.

This event utilises a different area of the Gatcombe Park Estate to that used by the Festival of British Eventing, which takes place in August.

Gatcombe Park is situated at Hampton Fields, mid-way between Minchinhampton and Avening; the event will be signposted from both directions.

Spectator admission is £5 for a car and occupants on each day. For more information including the full entry list visitwww.gatcombe-events.co.uk
