First and second from Sunday week’s Capalaba Final will be ushered through to the National Straight Track Final over 350 metres, to be contested at South Australia’s Murray Bridge course on August 24.
Last year Valhalla won the Queensland straight track crown, with Jamie McHugh’s Bye Bye Raider second.
Both contested the Nationals at Victoria’s Healesville track with Valhalla placing fifth and Bye Bye Raider sixth behind Jason Thompson’s straight track superstar Unleash Collinda.
Tzouvelis believes Valhalla still has a Nationals win in his repertoire.
“Right now he (Valhalla) is not at his peak, but he could be by the time the Nationals are held,” Tzouvelis said.
“He is a little under-done for this Sunday, but he is a naturally strong dog.
“If he can go through to the Final then this race will give him that extra bit of fitness.”
