Human Powered Vehicle Racing returns to the Busselton Foreshore on Sunday August 18 when the fastest human powered vehicles in Australia hit the Geographe Bay Street Circuit.
The event is Round 5 of the University of SA Australian Human Powered Vehicle Super Series.
A record 49 entrants will form up on the grid and take the green light at 10am to battle fatigue and each other over the 6 hour endurance event.
Series chairman Andrew McLachlan said Busselton continued to impress as a location and track for HPV racing.
"The support received from the City of Busselton and community has made this event a reality and it continues to grow, as we see increasing entries locally, from Perth, and interstate," he said.
City of Busselton mayor, Grant Henley said this would be the sixth year Busselton hosted a round of the series, and they were are pleased with how it has developed.
"It certainly brings in significant visitation to the city, provides a positive economic impact and brings colour and excitement to the foreshore," he said.
"We are looking forward to hosting the event and working with Andrew and his team again this year."
While many teams will take the 220 kilometre journey south from Perth, Busselton itself was well represented.
Georgiana Molloy Anglican School team manager Phil Deroost said his team were ready for the event.
"We have two HPV's in fine tune and entered in the S2 Category," he said.
"This is a big weekend for the squad, it's the culmination of many months of dedication and commitment by the students.
"We'll also have family members joining us over the two days in various support roles, so it's a real community effort.
"That's one of the many benefits of being involved, it brings a lot of people together in a team environment."
Other entries will take a longer route west across Australia's vast Nullarbor Plain to race alongside the Indian Ocean.
Fast Cats Racing's team manager David Poole said they had three vehicles heading over from Adelaide.
"One has been freighted over in advance, and another two leave on Monday," he said.
"We'll have a total of 11 riders and staff flying to Perth, then driving to Busselton for the weekend. Everyone's really looking forward to it."
Teams can have up to 20 riders in the younger divisions to share the cockpit duties, with less in the older and open categories, providing a real test of endurance.
