Tai Woffinden is hoping to put a «really bad» start to the Speedway Grand Prix season behind him and climb back up standings starting in Cardiff. The Welsh capital welcomes the riders back for round six of action after a mid-season break and three-time world champion Woffinden is hoping to improve on his current sixth place standing at close the gap on championship leader Bartosz Zmarzlik. Ad With five races down and five races to go, Woffinden sits 28 points behind his Polish rival but encouraged by his performances with club side Wroclaw in the PGE Ekstraliga, is hoping to lay down his championship credentials with a strong performance in the latest round of action at the Principality Stadium.
