Consisting of eight hours of racing around an 8km track at Jack's Point, the race is a social event for relay teams and a serious challenge for hardcore individual racers.
Organiser Geoff Hunt said yesterday everything was "looking good" for Saturday, with mowing and weed-whacking adjustments complete.
"We have not had much rain this winter and the whole area is drier than I have seen it," Mr Hunt said.
"The muddy ditch this year is completely dry, so we should have some quick times." Competitors will try to complete as many full laps as possible of the course.
"The thing about the race is that it's a very social event ... and when competitors tag their team-mates the other team-mates hang around the base camp and the energy and ambience there is great," Hunt said.
Pit-stop support is very much encouraged. Set-ups in previous years have included tents, supplies of cold beer and the occasional couch.
Hunt expected similar numbers to last year's race, which drew more than 50 competitors and was won by individual rider Jim Hawkridge, of Queenstown, who completed an exhausting 16 laps.
Hunt was unsure if the champion would return to defend his title this year, but the event will see national women's mountain biking champion Kate Fluker, also of Queenstown, compete.
Tour de Wakatipu winner Mark Williams will also be among top riders aiming for the title.
Registration costs $65 per adult and $45 for juniors.
