The list of stars set to be offered at the Tattersalls December Mares Sale continues to grow, with the announcement that the G1 Irish Oaks runner-up and G1 Prix de Diane third Inis Mor (Galiway) will be offered as part of the Sceptre Sessions.Trained by David Menuisier for Quantum Leap Racing, Inis Mor has been a model of consistency at a high level in 2026. The daughter of Galiway won the Listed Height of Fashion Stakes at Goodwood in May, beating the subsequent G2 Ribblesdale Stakes winner Earth Shot, before finishing a close third in the Prix de Diane at Chantilly behind Diamond Necklace. She then secured another Classic placing when second in the Irish Oaks at the Curragh – behind fellow Sceptre Sessions entry Johanna Walsh – and was last seen filling the runner-up spot again in the G3 Princess Royal Stakes at Newmarket.Inis Mor is out of Mellow, a winning daughter of Deep Impact and the dual Grade I winner Harmonious (Dynaformer). She possesses an official rating of 109.Syndicate manager Niall O'Connor said, “Inis Mor has given our partners some fantastic days out over the past two years all over Europe, and it has been a great thrill to see her placed in both the French and Irish Oaks. She looks a filly of exceptional potential and will, in time, make a wonderful broodmare for any breeding operation.”Tattersalls managing director Matthew Prior added, “The list of exceptional fillies and mares catalogued for the Tattersalls December Mares Sale continues to grow, and Inis Mor is an exciting addition to the Sceptre Sessions.“Quantum Leap Racing are no strangers to the sale, having sold Tamfana last year, and it is a wonderful achievement for the syndicate to have another filly of such ability. We look forward to showcasing her to leading names in the racing and breeding world.”The post Dual Classic-Placed Inis Mor Joins All-Star Cast for Tattersalls Sceptre Sessions appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
