"We haven't seen it as an issue at any stage in his preparation. He's been 100 per cent sound all the way through. It's really cool that we've been able to hang on to him."
Explosively's dominant trial victory at Taupo looks even better in hindsight, with runner-up Cheaperthandivorce winning stylishly on debut at Rotorua on Wednesday.
"His trial was the quickest all day at Taupo, even better than the open-class horses," Ralph said. "And the good win the other day by Cheaperthandivorce has really franked that form.
"That trial performance gave us a bit of confidence leading into his debut race at Te Rapa, and we were expecting him to do much the same thing there. It doesn't always happen that way in racing, but on that occasion it worked out exactly as we'd hoped. We knew we had a horse who could jump and run, and that's what he did.
"Everything's been really good with him since then. We've given him only one real gallop in between times. He's not a big horse — he's struggling to weigh 440kg.
"A few possible buyers have been turned off by his size as well, but size never bothers us. It's the motor that counts.
Ralph has no fears about today's step up in distance.
"We feel that he's not limited to 1200m, and that he'll have no trouble doing 1400m on Saturday".
