This will be Newburn's fourth charity run at Manfeild having completed two 72-hour and a 48-hour runs in the past four years.
Last time Newburn raised about $3500 for charity and he had a similar goal this time.
The 62-year-old is aiming to cover about 190km over the 24 hours but said this run was not about record setting. He's done plenty of that before.
In 2013 he ran 487km in 72-hours which was a New Zealand record for distance run without sleep.
In 2014 he set the masters world record - and one of the top five times overall - for running from New York to Los Angeles, crossing the United States in 51 days, 16 hours and 40 minutes.
Newburn is using tomorrow's run as build up for bigger goals towards the end of the year including a Cape Reinga to Bluff run.
"I'm looking at 17 days for that," Newburn said. "I've already got a driver so I just need to hit up a few sponsors to cover a bit of cost.
"I'm getting pretty close to where the endurance was before the States."
Newburn will set off on 8am this Wednesday and will cover probably more than 60 laps of the track over the 24 hours. He has support runners to keep him company during the night.
"I know every direction to go and the best way to go around that track," he said. "I probably know it more than most car drivers."
Newburn is encouraging people to come along and have a go themselves, even if it's just one lap.
"The more the merrier. I'll be down their rain, hail or shine. It's all fun."
