Victoria Pendleton's Cheltenham Festival dreams suffered a potential jolt after she was unseated in a point-to-point at Kingston Blount on Saturday.
Just days after winning a first race as a jockey at Wincanton, the double Olympic cycling champion was riding the Alan Hill-trained Supreme Danehill when she lost a stirrup after jumping the third fence from the finish and came out of the saddle.
Hill's wife, Lawney, has been one of Pendleton's chief mentors during her Betfair-backed 'Switching Saddles' challenge since it was announced last March that she would make the transition from velodrome to racecourse.
She said: "Unfortunately she's had a fall, but she got up and walked away and is perfectly all right.
"The horse pitched on landing after jumping the third-last. She did well to stay in the saddle, but unfortunately she lost one of her irons, became unbalanced and gravity won.
"After jumping the third-last they turn into the straight and I'm afraid it's quite difficult to steer when you've only got one stirrup.
"It's unfortunate as she was having a great spin up until that point and I think she would have won as the horse was flying and the leader was stopping quickly.
"It was a novice mistake and these things can happen with novice riders.
"It was something only an experienced rider would have been able to cope with."
A press conference will be held on Monday to announce whether or not Pendleton will fulfil her ambition to ride Wincanton winner Pacha Du Polder in the St James's Place Foxhunter Chase at Cheltenham later this month.
