SIXHILLS was trained by James Fanshawe for her owner/breeder Dr Catherine Wills. The daughter of Sabrehill (Diesis) won at three and she comes from a family that Catherine had many strands of and which has produced many tough, durable winners.

The dam of Sixhills was Moidart (Electric) and her half-sister Rynechra (Blakeney) bred a couple of stakes winners and the Group 2 Park Hill Stakes runner-up Applecross (Glint Of Gold). The latter enjoyed great success as a broodmare and bred, for Catherine Wills, the likes of Group 1 Prix du Cadran winner and Ascot Gold Cup runner-up Invermark (Machiavellian) and the Group 2 winner, Grade 1 runner-up and successful National Hunt sire Craigsteel (Suave Dancer).
