Crambo repeated his victory of last year when grimly holding on to win a second Howden Long Walk Hurdle at Ascot on Saturday.

Since his victory in the race 12 months ago, his career had been in danger of coming off the rails, having disappointed at Cheltenham and Aintree.

Trainer Fergal O'Brien had wanted him to reappear at Newbury last month but he was not quite right, so it meant that he was having to take on race-fit rivals in a Grade 1 on his seasonal return.

Sent off at 9/1, Crambo had plenty to do jumping the second last before his stamina kicked in.

The race had been taken along by Beauport, better known as a chaser, and as he was given such an easy lead, at the second-last flight it appeared he had slipped the field.

He was still in front jumping the last, but perhaps cleared that obstacle just a bit big, which gave Crambo the chance to draw upsides.

Once Jonathan Burke had mastered him, there was a new danger, as Henry de Bromhead’s Hiddenvalley Lake put down the final challenge, but he just failed by a head. Beauport stuck on for third, with The Wallpark fourth.

The favourite Strong Leader was one of the first beaten and never looked like winning.

"It’s been a tough time, horses haven’t been firing and we’ve had a change of jockey. We’ve been getting it from all angles," said O’Brien.

"The horses haven’t been quite right but the winning of this race was not running at Newbury, I knew we could get him better. I knew he likes the track here.

"If we were going to see the old Crambo, the best place to come was here. I couldn’t do it without the owners, I’m so grateful to Chris (Giles, owner) for letting me wait and come back here. He’s shown us what we wanted to see today.

"Johnny will be a big part of where we go next, he’s the one who is riding him and he’s the one who knows how he felt at Cheltenham last year.

"I genuinely think we had a good first half of the season and then the wheels fell off, I was a bit disappointed in myself for running him at Aintree but he’s come back here today and he’s shown what he can do.

"This job brings its own pressures but as a trainer, you put pressure on yourself, because you want to do well, for your owners, for your staff, for everyone else.

"They haven’t been quite right but we’ve always kept the belief in our system."
