Eight contenders will go for glory in Fontwell Park's Southern National on Sunday.
Final declarations have left a stellar field in place for the 2.40pm contest, one of the highlights of the track's annual programme.
Potters Approach, to be ridden by Connor Shoemark for trainer Dan Skelton, will go off as one of the favourites for the three mile, three furlong test of stamina.
Robert's Star (Sean Bowen / Mark Bradstock) is another likely to be vying for market leadership. Bowen won the race last year on the Anthony Honeyball-trained Cresswell Breeze.
