Infallible could drop back to seven furlongs for the Betfair Cup at Glorious Goodwood later this month if she is none the worse for her game effort in the Falmouth Stakes.
The John Gosden-trained filly was second to Nahoodh in the Newmarket Group One on Wednesday after occupying the same position in the Coronation Stakes and finishing fourth in the 1000 Guineas.
Both her wins have come over the shorter distance but an appearance in the race registered as the Lennox Stakes would see her taking on the colts.
“We’re not quite sure where we go next with her, but we are looking to other options now as regards trip,” said Chris Richardson, managing director of the owners, Cheveley Park Stud.
“The Lennox Stakes at Goodwood might be an option but obviously we’ll see how she is.
“That’s not too far away. We’ll just let her get over that and see if John feels if she’s going to be ready to comeback as quickly as that or whether we wait a bit longer.
“Certainly, we are going to look at the options over six and seven furlongs.”
Spacious, who carried the Cheveley Park colours into second place in the 1000 Guineas and fourth in the Coronation for trainer James Fanshawe, is being given plenty of time to regain her best form.
“The Guineas took a lot out of her and she didn’t quite sparkle at Ascot,” Richardson added.
“We are going to take the long-term view and let her come back when she’s ready. She’s a filly that will be likely to stay in training next year all being well.
“We’re not going to rush her. When she’s ready she’ll tell us.”
