The four-day inaugural Challenge Bathurst kicked off on Thursday at the iconic circuit, with drivers from across Australia and the world taking part.

Unlike other events at the Mount, this is not a race, with drivers given the opportunity to road test cars, equipment and themselves.

Brendan and Tristan will get six 20 minute session each across the weekend in their 1995 Nissan 180 SX.

“This [Mount Panorama] is heaven on earth, just don’t tell the missus. It’s the pinnacle of motorsport,” Brendan said.

“This will be the first time driving it so the nerves are getting high.”

When asked when they hope to achieve while speeding around the circuit, the brothers both have different aims.

“I’m just hoping to get around the track for the first time,” Brendan said.

“I want to get 240km/h down the straight,” Tristan said.

The duo said the $1600 entry fee for the two-day Regularity event made it affordable for average motoring enthusiasts.

The brothers said while they have been to the Mount for the last five Bathurst 1000 events, this will be the first time they have ever driven at speed around the circuit.

Challenge Bathurst has brought an influx of people to the city for the week, with many of the 325 drivers entered, and their pit crews, camping on the Mount.

Entry is free for spectators.
