The second running of the Kokoda Track race in Papua New Guinea from Saturday will see 42 people attempting to be the fastest over the route made famous by Australian diggers in World War II.
Three PNG nationals last year became the first to walk the track under 24 hours in the inaugural challenge race from Kokoda to Owers Corner.
John Hunt Hiviki from Kebara near Kokoda, walked the steep and arduous 96 kilometre track in 22 hours finishing ahead of 25 people.
This year's winner will pick up prize money of more than one thousand US dollars, with another one thousand for setting a new time.
Race organiser, Gail Thomas of Kokoda Trekking, says the event will be positive for PNG's tourism sector.
And, she says she is expecting a big turn out for the race.
"Kokoda will be alive on Saturday and Sunday and it will be bigger then Ben Hurr in Kokoda, and it will be the biggest thing Kokoda has ever seen."
