Apprentice Baylee Nothdurft can complete a big week with the plum ride on favourite Mr Marbellouz in the Listed Goldmarket at the Gold Coast.

Nothdurft, who rode a double at Eagle Farm last week, won a heat of the National Apprentices' Challenge series at Ascot in Perth on Wednesday.

His mount Fearhildi was a $31 chance but responded to a top ride from Nothdurft.

Nothdurft finished third on his only other ride at the meeting.

A win would give the Toowoomba apprentice his first stakes winner and Mr Marbellouz is a warm favourite in the race which is one of the oldest on the Queensland racing calendar.

Nothdurft still has a 3kg claim but Mr Marbellouz's trainer Kevin Kemp has full faith in him.

"He won on Mr Marbellouz last start and knows him well," Kemp said.
