Martyn has been involved in horses all his life, not only in racing but as a keen polo player and Master of Foxhounds. Martyn trained his first National Hunt winner under rules back in 1972.
Since then he has trained numerous winners under both rules. Having concentrated on flat racing since the late 1980s, he has had multiple stakes winners and boasts a very impressive strike rate with two year olds, most notably the seven-time winner, Lunar Mist.
The move to Sefton Lodge in 2014 marked the beginning of a new era with a commitment to producing top-class winners. In addition, Martyn is also at the forefront of The Snailwell Stud, which provides the perfect environment for broodmares and stallions, preparation for the sales and the resting and breaking of yearlings.
