"The track was extremely slick in places with the hard-packed clay offering next to no bite for my tyres. But I soon began to open up a lead.
"A couple of missed turns resulted in brief moments with me being lost and further down the track having to stop to open a closed farm gate put a dent into my lead, but I kept the heat on and was able to maintain my spot at the front," he said.
Whibley said the opening 32km lap took about 45 minutes as the slick conditions slowed everybody down but still managed to build up a 30-second buffer over the chasing bunch.
"On the second lap, the track had cut up a lot and some of the steep hill climbs had some very big ruts. One bog at the top of one of these hills was also giving some riders fits, it also claimed Adrian on the second lap, with him getting buried up to the seat of his bike and taking several guys to get it out," Whibley said.
"But I continued out front, stretching my lead lap after lap as I got used to racing some fast farmland again."
With Whibley so far in front, he was required to complete an extra lap, coming through the lap-score area with time still left on the clock. But it was a trouble-free run for him to the finish, the only rider to complete five laps in the three hours, with Johnston, on a Yamaha YZ125, eventually finishing runner-up.
Not content with winning on Saturday, Whibley headed to Wairarapa on Sunday to tackle round two of the Bush Riders Cross-country Series near Pahiatua. Again he had to deal with tricky conditions, light rain and galeforce winds, making the course particularly challenging.
Whibley was in command, this time winning ahead of Taranaki's Smith on a Yamaha YZ250F, with Wellington's Hugh Lintott, aboard a Yamaha YZ450F, taking third place overall to make it a clean haul of placings for Yamaha riders.
