Star three-year-old All Too Hard will mount a lone challenge for his age group when he contests the $500,000 Futurity Stakes at Caulfield on Saturday.

Black Caviar's half-brother is one of 10 acceptors for the Group One sprint over 1400m.

All Too Hard, a first-up winner against older horses in the C F Orr Stakes at Caulfield on February 2, has drawn well in barrier four.

The Caulfield Guineas winner will have last year's Melbourne Cup hero among his rivals.

Green Moon has drawn barrier one with his Melbourne Cup-winning rider Brett Prebble making the trip from Hong Kong to take the ride.

New Zealand warhorse King Mufhasa (barrier seven) is another notable entry.
