IT IS one of Maryborough Speedway's biggest weekends since the new season started but it is shaping as a preview of even bigger dates to come.
The JTR Team Challenge has attracted some of the state's best riders.
The likes of Zaine Kennedy, Tyson Snow and Maryborough boy Joel Coyne will light up the track tonight as part of the innovative team-based competition.
Riders engage in an epic, 500cc-powered chess-like game of smarts.
Points are awarded for the first three finishers in each race, with the team who earns the most amount of total points named the event's winner.
It means the team manager must consider the strength, speed and skill of opposition team's riders when they nominate a rider for each race.
While 16 riders will represent New South Wales, South East Queensland, Central Queensland and Far North Queensland in the 500cc teams event, there will be plenty of action in the support solos and sidecars.
More than 10 riders have nominated for the 500cc support race, while Brock Tregea and Jacob Hook will battle in the 250cc class.
Seven duos have nominated for the sidecars, in what is a preview of the November 18 Qld Sidecar titles, which will be held at Maryborough Speedway.
The solos riders will earn valuable time on the host track for the Queensland titles, which be held on December 9.
Gates open at 1pm, practice from 4pm and racing from about 5.30pm.
On Sunday, drivers will travel from as far as Brisbane to compete in the karts competition.
Competition will cover each class, as drivers get more practice ahead of the state titles in Ayr.
The karts will start racing at 10am on Sunday.
