DON'T let anyone tell you the trivia game isn't tough.

In fact, it's keeping Mitchell McAulay-Powell up at night.

The Rockhampton-based trivia guru, who runs trivia nights at Lightbox and the Harvey Road Tavern in Gladstone, is recovering from a world record attempt at hosting the longest marathon as a quiz master.

Aided by two teams, a suite of official witnesses and a volunteer helper who passed out standing up, he managed to keep the marathon going for 33 hours and 19 minutes - a solid 11 minutes past the previous record.

"My sleep patterns are completely out of whack," Mr McAulay-Powell told The Observer.

"I'm going to bed about midday and waking up at 7pm... when I do go to sleep all I dream about is trivia. It's quite interesting.

"I wake up sometimes thinking there's still a timer going off, thinking I've missed a question."

The record attempt was originally intended to be a two-person race - but Mr McAulay-Powell's business partner James Law had to pull out due to a shortage of independent witnesses.

All that remains now is for the record attempt to be officially confirmed by Guinness World Records.

The entire attempt was filmed for verification - using four cameras from a home security system plus a webcam, video recorder and the Allenstown Hotel's CCTV - but the event did not go off without a hitch.

"The TV with the timer on it went off for about four or five seconds," Mr McAulay-Powell said.

"So there'll be footage of us scrambling around like crazy to fix it.

"I was a blubbering mess by the end of it, (due to) the combination of exhaustion and being a bit paranoid it wouldn't count.

"But I've looked at the rules and now I'm quietly confident."

The event raised more than $500 for the Leukaemia Foundation's World's Greatest Shave - part of Mr McAulauy-Powell's ongoing efforts to raise $3000 by March.

If successful, his beard will be dyed blue to match his hair, which marked the halfway point earlier this month.

"I have a feeling my beard will be blue very soon," he said.
