In fact Denyer, who will share the #29 Trofeo Motorsport Lamborghini Huracan GT3 with Dean Canto, Liam Talbot and Marcel Zalloua, feels the predicted high temperatures for the duration of the event will test even the fittest of drivers.

"I reckon one of the biggest challenges is just going to be surviving the conditions, just looking at the temperature forecast for the next couple of days, it's actually pretty scary," he said.

"So when you're in the car, it's 25 degrees plus on top of the ambient temperature, so you're talking 65 degrees inside the car."

Though he will probably face some brutal hours in the seat of the Lamborghini, the predicted high temperatures are not enough to dampen his enthusiasm of forming part of the 12 Hour grid.

"I'm really pumped. Naturally it's my home event, I can see the back of the mountain from my house, I feel that magnetic calling of the place. It's my spiritual home for more reasons than just family."

It will be his ninth start in the annual enduro, which has already seen him snare a class win and another three class podiums.

He has steered Mitsubishi Lancers, a Subaru Impreza, Ford Focus, Porsche 997, Ferrari 458 and a McLaren 650s.

The race itself will begin at 5.45am Sunday.
