More than 50 competitors from across the country gathered at the scenic Jacks Point to battle it out on the purpose-built 7.1km Stragglers Loop track.
Riders had to complete as many laps as possible in eight hours and Hawkridge won the individual open men's title by reeling off 16 laps.
Organisers said he was the only rider on a single-speed bike.
"I finished second last year but this year I felt more in control . . . I'm sure next year I can push it out to 17 laps," Hawkridge said.
For the second edition of the annual competition, race director Geoff Hunt said the number of racers had more than doubled from the first year.
"We were all pleased with the turnout this year and the weather played a big helping hand."
Hunt said Hawkridge and another Queenstown multisporter, Marty Macdonald, fought out an all-day battle for the top spot.
Macdonald completed 15 laps before the siren sounded at 6pm.
Individual competitors and teams of two, three or four took part.
Cromwell multisport athlete Sarah Fairmaid was the top female, completing 12 laps to finish well ahead of Yvonne McDonald (also of Cromwell), who finished second after completing nine laps.
In the junior category, Nicole Shields (11) and Hamish McHugh-Smith (12) represented Clyde Primary School as a two-person team and clocked a respectable 10 laps.
In the teams sections, riders took turns to complete single laps.
Team JRW completed the most laps (17) to win the mixed division from ABIFasterTFC (16).
Rogue Mantis also finished 16 laps, less than six minutes behind, to bag third.
One of its riders clocked the day's fastest lap of 24min 19sec.
Maltys Maverick completed 16 laps to win the open men's division from Zookeepers and The Inhalers (both 15).
Two Old Roosters and a Mountain Goat (14 laps) won the veteran men's section, while De-Funksters (10 laps) were the top veteran women.
Queenstown Pedallers-the Hounds completed 14 laps just 1min in front of rival team Queenstown Pedallers-Over the Hills to win the veteran mixed section, while race sponsor Team Patagonia finished a close third, also completing 14 laps.
Hunt said the increased attendance this year and overall success of the event had motivated him to organise the competition again next year.
"It worked really well, everyone was covered in mud and covered in smiles," he said.
The 8hrs@Jacks event helps to promote the work of the Wakatipu Trails Trust in developing trails in the district.
