Haydock Sprint Cup
Kyllachy was retired from racing to become a breeding stallion at the Cheveley Park Stud in Newmarket. He had considerable success as a sire, with his progeny showing their best form over sprint distances. The best of his offspring have included Sole Power, Krypton Factor (Dubai Golden Shaheen), Dim Sum (Chairman's Sprint Prize), Twilight Son (Haydock Sprint Cup), Arabian Gleam (Challenge Stakes), Tariq (Lennox Stakes), Penitent (Joel Stakes) and Stepper Point (Sapphire Stakes).
