But the Canberra race car driver is going to relish every bend as he prepares to launch his third Porsche Carrera Cup campaign in the opening round at the Adelaide 500 on Friday afternoon.

Hill is determined to climb up the rankings this year having finished sixth last season - up from ninth in 2018 - but he admits that doesn't stop the nerves from kicking in late in the week.

"Adelaide is a very daunting track, it's a street circuit so it's very rough," Hill said.

"We don't get to test there at all, so you only get to see it once a year. Definitely having two years of experience there now is going to help me a lot when I get there.

"You're still preparing yourself from a driving and a car set-up point of view in your testing, but you still have to be able to respond quickly to what you're faced with when you get there.

"It's massively a team sport. All people see is us driving on the track, but so much goes on behind the scenes.

"Of course, a goal for us this year would be to really challenge for the title.

"Judging off last year's results and the speed we had at a few events at the end of the year, I'm really hoping that's going to put us in good stead to challenge the fast guys."

Perhaps now more than ever it is vital for Hill to have the strong fitness base so many drivers desire.

Because on an unfamiliar road like the one he greets in Adelaide, one wrong decision under fatigue could throw his season opener into disarray.

"You do need a really good fitness base, it's a pretty harsh environment in the car," Hill said.

"It's normally about 20 degrees hotter than the ambient, so it could be 60 degrees in the car and your heart rate is probably up at around 160 or 170, and that's a combination of adrenaline and the physical exertion.

"More than anything, it's just a matter of being able to have that endurance. If you start to fatigue, you make bad decisions."
