On The Fringe is one of 36 horses left in the St. James's Place Foxhunter Chase following the six-day entry stage.
Enda Bolger's charge won the race last year and heads the ante-post betting. He is set to be ridden by brilliant amateur Nina Carberry.

Victoria Pendleton's mount Pacha Du Polder will attract much of the attention in the race.
It was confirmed earlier this week that the dual Olympic cycling champion would achieve her dream of riding at the Cheltenham Festival, having bounced back from a Fakenham fall by guiding Pacha Du Polder to a wide-margin success at Wincanton.
At a press conference to confirm her participation, Pendleton said: "If I get round on the horse and complete the course I'll feel like that's a gold medal."
Pacha Du Polder is a best-priced 20-1 for the amateur riders' Gold Cup on Friday.
Along with Pacha Du Polder, the home team includes Warren Greatrex's Paint The Clouds and Mendip Express from Philip Hobbs' yard.
