DAN Curran attaches oxygen tubes into the back of his helmet.

They let him breathe when dust and mud fly through the open windscreen of his 4x4 buggy, as it races at up to 100kmh over dirt jumps.

At the CQ Bikes Bulls Buggy's and Bands event at the weekend, Mr Curran described the races as "surreal".

"When you got the visor down and air hose connected, there's not a lot of noise," he said.

"The only way you know you're going fast is because the trees are going by so fast.

"I've rolled before, but have never really got hurt."

Mr Curran raced his little brother's car, while his dad John and eight-year-old son Zeke came along to support.

"I took the kids for a ride the other day, one had to use a booster seat," he said.

"Zeke's not allowed to race, but when he got out he said 'Is that it?"

Mackay's Clinton Frank said he would usually wear goggles for an enduro-cross event, but it was so muddy he couldn't see the point.

"It went well though, until I fell off," he said.

"Another bike came up behind me. I couldn't see in the mud so I just closed my eyes."

Kane Hall also came from Mackay to compete in the enduro-cross.

He's competed at national events before, but said the CQ Bikes Bulls Buggy's and Bands track was technical.

At the mud buggies, Tye Hourigan and Christian Ellis said the event had gone well although they were "not racing for sheep stations".

"My bomb went well until the clutch, gear box and engine broke," he said.
