Nina Carberry will bid to become the first female rider to win the John Smith's Grand National when she partners Organisedconfusion for her uncle Arthur Moore at Aintree on Saturday.
Carberry won the Irish Grand National on the same horse last year.
"Touch wood everything will go right now until the day, he'll stay sound and he'll be there in the line-up. He'll have a chance," she told At The Races.
"Hopefully he takes to the jumps. Hopefully he'll be there at the end and he'll be good enough.
"He jumps well at home and he's jumped over a few of those fences, but you just don't know until you line up with the others.
"It's who takes to it the best, and you need luck on your side as well."
A decision on whether Le Beau Bai runs in the Grand National will be made at the last possible moment.
Winner of the Welsh National in December, Richard Lee's nine-year-old is at his best when the mud is flying.
After 11 millimetres of rain in Liverpool on Monday, more is forecast throughout the rest of the week.
The ground is currently soft on the Grand National course but that might not be wet enough for Le Beau Bai, who was third to Giles Cross in the National Trial at Haydock last time out.
"It might not be soft enough for him at the moment. I'm sending somebody to walk the course for me on Wednesday," Lee said.
"He'll only run if it's soft or worse, all his wins have been on soft ground and he just doesn't let himself down on anything quicker.
"We'll probably not decide until Saturday morning, which I know doesn't help anyone, but we have to do what's best for the horse."
