Trainer Tony Pike and winning rider Vinnie Colgan have slightly different opinions.
After Rangipo won yesterday's $100,000 The Hits Great Northern Guineas (1600m) Pike offered his opinion that the 3-year-old would stay the 2400m of the Derby distance in March.
Colgan is nowhere near as sure. "I think up to 2000m he'll be fine, anything further than that and it might be open to question."
Rangipo is by a sprint sire in Stryker, but is bred from the Zabeel mare Holloway. There is a line you could put a jersey bull over a Zabeel mare and breed a winner.
"He's always given me the impression he'll get a staying trip," said Pike. "He has a sharp turn of foot and relaxes. He cleared the gates quickly today and Vinny dictated the pace outside the leader and he relaxed."
