The six-time winning chaser started out life winning over fences at Market Rasen off a mark of 110 back in March last year but now finds herself stepping up in Listed company with a rating of 140, following some impressive performances over the larger obstacles.

She was pulled-up on her only other start at Listed level at Huntingdon in January but hit the ground running this season when a commanding four-length winner of a competitive handicap chase at tomorrow's venue on her seasonal reappearance, making it a perfect three from three at the Lincolnshire track in the process.

Martin Keighley said: "It was a really good performance, her first run of the season at Market Rasen,"

"That was quite a strong handicap, and she did it well, as soon as she won there, we had this in mind as we're desperate to get her some black type.

"We've saved her for this race and hopefully she can, she's been to the track twice and won there twice, she'll like the decent ground so I'm hoping for a big run."

Found On will face just four rivals in her bid to remain unbeaten at Market Rasen tomorrow, with Keighly pointing out the Dan Skelton-trained Galia Des Liteaux, who is a Grade 2 winner over fences, as the horse they all have to beat.

He added: "The Dan Skelton horse will be a hard one to beat, but she's [Found On] in good form and if she doesn't win and is in the first three, it will be great to get her black type."

Tweed Skirt, Burrows Diamond and the Jedd O'Keeffe-trained Fairfield Ferrata complete the line-up, with Galia Des Liteaux a general even-money favourite to land the Listed prize tomorrow.
