Whanganui trainer Kevin Myers chases a repeat of the Waikato Hurdles and Waikato Steeplechase double he won last year.
Sea King should mount a stout defence of his hurdles title and was at $2 yesterday and stablemate Mahanadi was a $3 favourite for the Waikato Steeplechase.
Mahanadi is making his debut over country but has an outstanding record as a hurdler and has measured up in good company on the flat.
He has won three of his four hurdle starts, including the Grand National Hurdles, and finished fourth in the New Zealand Cup in November.
He has been well schooled over country, with "three or four" steeplechase trials and a win today would encourage Myers to send the horse to Melbourne for the Australian Steeplechase.
Sea King is unbeaten from two starts at Te Rapa and has had six wins and five placings from 14 runs over fences, though he can be a difficult ride.
He has been frequently mentioned in stipes' reports for his tendency to over-race and either lug out or lug in and Myers is wary of predicting how he will behave.
"He looked good when I put him on the truck today but you wouldn't know what he might do."
Myers, who likes to help out the country clubs, will have six runners at Riverton on Monday including Atomic Road in the Great Western Hurdles and Roodyvoo and McCulley in the Great Western Steeplechase.
Roodyvoo, who raced on the flat at Timaru yesterday, did not race last winter but has had three wins and three placings from seven steeplechase starts.
He was the runner-up in the 2012 Australian Steeplechase and a couple of months later won the Koral Steeplechase at Riccarton and finished third, beaten less than six lengths, in the Grand National.
