GSR Thoroughbreds is run by fully qualified, professional horse people, with over 40 years worth of experience in breeding and training racehorses. We are a friendly, family owned and run establishment, with a dedicated, caring staff. The team is headed by Geraldine Rees, who is assisted by her father, Captain Jim Wilson and her staff; Amanda Miller, Lesley Braddock and Gemma Jones.

Geraldine moved up through the Pony Club ranks to be selected for the British Junior Three Day Event Team in 1973. The Team, led by Virginia Holgate, won the Junior European Championships in France that year. Later Geraldine won the Midland Bank Trophy at Tidworth, as well as completing Badminton several times and representing Great Britain as a Senior.

In 1976, Geraldine joined her father, racehorse trainer and breeder, Captain Jim Wilson as Assistant Trainer. During this 22 year partnership they trained many well known winners on the Flat and over Jumps including Twidale and Red Rosein (winner of the 1992 Wokingham Handicap at Royal Ascot). Whilst assisting her father, Geraldine was also twice Lady Amateur Champion and was the first lady to complete the Grand National in 1982.
