"The crowd was chanting him down the hill," said co-organiser Leighton Minnell, the world champion jetboater. "He was the first one to go off the ramp, over the ramp, through the ramp, crashed on his head, he went through eight wheels.
"Three to four thousand people chanting 'Panda, panda, panda!'."
Doyle agreed going into the race his official costume was not the most conducive to competitive racing. "I knew that, I didn't really have much choice in what I got to wear."
Wanganui Chronicle's own Viv Johnson received a similar prize for his massive prang straight into the tarmac.
The derby idea was hatched by Wanganui speed freaks Minnell, racer Mick Paul, who is after Burt Munro's land speed record, and More FM radio host Jason Granville.
Minnell and Granville said with the experience of the debut event under their belts, it will definitely be back in 2014.
Minnell said he knew schoolchildren and a number of kids-at-heart are already tinkering away in their sheds for next year.
