White Star Line and Carlingford Lough, the first two home in last year's Guinness Kerry National, are among entries 38 entries for this years's renewal at Listowel on 17 September.
The John Kiely-trained Carlingford Lough, who has been allotted top weight of 11st 10lb, failed by just five lengths to give White Star Line 17lb last September
The eight-year-old is reported be in good shape after a mid-season break and is an intended starter.
"He has had a good break and if John (Kiely) is happy with him, the plan is that he'll run next week," said Frank Berry, racing manger to owner JP McManus.
McManus has other possible runners in the three-mile handicap chase in the Tom Mullins-trained Alderwood, Lucinda Russell's Tap Night and Jacksonslady from Philip Dempsey's stable.
As well as White Star Line, Dessie Hughes also plans to run Golden Wonder, who was sixth in the Galway Plate.
"They are two fresh horses and this race has been the plan for them for a while," said Hughes.
"Golden Wonder ran a good race in the Galway Plate, but the trip was just a bit short for him and three miles around Listowel should be fine.
"White Star Line won the race last year and he would like a bit of decent ground. They are both in good shape."
