While drivers sweltered in stunning heat, Kayo Sports was running an incredible competition.

After calling out for entries, 25 people had the chance to win a Holden Acadia valued at $65,000.

The “Can’t Take Your Hands Off Kayo” challenge had the 25 challengers tested mentally and physically with the simple aim for the competitors to keep a hand on the car for longer than everyone else.

While not hitting world record status, the challenge lasted an incredible 57 hours and 27 minutes.

That’s just under two-and-a-half days.

The contestants were given a 15-minute break every three hours to go to the toilet and eat.

The winner was Sonia Terrington, a 42-year-old nurse from the north-eastern suburbs of Adelaide with a family of five.

At the 42-hour mark, there were just four contestants left — Josh Young, Connie Vosnakis and Terrington from South Australia, and Queenslander Sam McIntyre.

Terrington was interviewed at the time and gave away her secrets of staying awake for so long.

“I have 15 minutes so I toilet, I have a 10 minute little doze and stuff some food and off we go away again. Desperately want this car. This is like the GF for me,” she said.

“I’m naughty, every hour, I close my eyes and meditate for about 10 minutes so I reckon I’ve got a lot more sleep than others.”

With the timed breaks meaning everything away from the car needed to be done quickly, Terrington said it was a huge challenge with the competition finishing at 2.27am on Sunday morning.

“It gave me a lot of time to do some sorting in my head, I met a lot of good people, but it was tough,” she told The Advertiser.

“It was tough, physically and mentally, but it was better than I thought. The staying awake and staying motivated were the worst parts.”

Terrington’s insane act of endurance was incredible with the temperature surging to 40 degrees on both Friday and Saturday with fans to cool the contestants down in the tent.

But it wasn’t near the record.

In New Zealand in 2016, in near zero degree temperatures, a tennis coach kept going for 78 hours and nine minutes to break his country’s record to win a 2005 Honda Aria.

The world record time for a hand on car competition is 87 hours and 12 minutes held by a Singaporean competition winner.
