Lady Cecil hopes to replicate an early achievement of her late husband Sir Henry by winning the Cesarewitch on Saturday with Tiger Cliff.
Sir Henry, who died in June, won the Newmarket handicap in 1971 with Orosio.
"Henry has won it once. We'd settle for winning it once too.
Forty-two years in the making
Sir Henry Cecil's only win in the Cesarewitch came in 1971 with Orosio. Forty-two years later Lady Cecil will attempt to claim Warren Place's second success in the race with Tiger Cliff
"But we're really lucky because we've won races at Ascot, Goodwood, York. But to have a winner at Newmarket, which is our home track, would be fantastic," Lady Cecil told BBC Look East.
She took over at Warren Place following her husband's death and is currently
in the process of qualifying for a full licence.
Lady Cecil has saddled 33 winners in the past four months, including
the BetFred Ebor at York with Tiger Cliff,
who also won at Newmarket in May and could claim a handicap double on Saturday by landing the Cesarewitch.
"Any rain that comes will be much appreciated. He won at Newmarket on good to firm earlier on," added Lady Cecil.
While watching the four-year-old, owned by Henry Ponsonby, on the gallops on Thursday, Lady Cecil admitted that speaking to the media was part of the job she did not always enjoy, but she had found training the horses rewarding.
"This is the bit I really don't like. It's hard work but when you've got good people around you it's enjoyable," she said.
"Being out with the horses is the most enjoyable bit. It's definitely better than sitting at a desk."
