Simcock operates out of Newmarket in Suffolk, one of the most competitive training centres in Britain, and has sent out 39 winners already this season alone. That the yard keeps running King's Castle — and keeps finding races he can win — speaks to a clear understanding of where this horse is at his best. The answer, it turns out, is simple: give him normal ground, give him a long trip, and step back. On standard conditions he has won 5 of his 11 races, a remarkable 45% — nearly one in every two attempts. Over distances of two miles or more, he has won 4 of 10, or 40%. For context, most racehorses win somewhere between 10% and 20% of the time. King's Castle, in the right conditions, is nearly doubling that.
His most regular partner in the saddle is Miss Taryn Langley, who has ridden him 12 times and won on three of those occasions — that is 1 in every 4 races together, a 25% win rate that sits comfortably above the average. His career began at Newbury back in June 2022, and his most recent win came at Sandown Park in July last year. He raced just yesterday, which tells you everything about his durability at the age of nine.
Recent form reads: two wins, two third places, a fifth, and a second across his last six outings. He is not fading away — he is placing in almost everything and winning regularly enough to suggest there is more to come. He tends to race at Class 5 level, which sits in the lower half of the British racing ladder, and he has won 4 of his 14 races at that tier. That is not a criticism — it is smart horsemanship. King's Castle is a horse who wins races because his team understands exactly what he needs and makes sure he gets it.
