Coltherd Racing came into being in 1999 - the year Selkirk farmer Stuart Coltherd took out a permit to train his own horses. He gained his full trainer's licence in 2004. The operation is based at Clarilawmoor Farm, on the outskirts of Selkirk, and boasts facilities for 26 race horses. It is a dual purpose yard, catering for point-to-point, national hunt and flat racing.

Stuart's wife Lesley is joint partner in Coltherd Racing, while the couple's 18-year-old son Sam is a conditional jockey now based at Sue Smith's Craiglands Farm yard in Yorkshire. Sam has ridden 27 winners to date, and when allowed will still pilot horses for Coltherd Racing should owners so wish. Stuart & Lesley's elder daughter, Amy, helps out with stable and riding duties, while younger daughter Milly is still at school but already has a keen interest in the equestrian world.

In the last five seasons, horses from the Coltherd Racing yard have recorded a total of 57 wins from 468 runs - 39 coming in steeplechases and 18 over hurdles - plus a total of 75 placings. During this five-year period, Coltherd Racing's total earnings amounted to £361,713.
