Robert Britton prepared Iona Seven overcame an awkward box six draw to claim the $100,000 Sportingbet Paws of Thunder (520m) winners cheque, at Wentworth Park on Saturday night.

Setting a cracking pace, Iona Seven lead throughout posting sensational sections of 5.32 and 17.84 before stopping the clock at 29.56, 2 ¼ lengths clear of race favourite Punch One Out. Tasmania runner Buckle Up Wes finished strongly to claim third place.

Overwhelmed by the victory, the Sidrak family thanked mentor Robert Britton and told patrons trackside of the joy of breeding the litter and now claiming the first Group 1 at Wentworth Park for 2014.

Supporting the Paws of Thunder, the $40,000 to the winner, Sportingbet Summer Plate drew together a host of staying stars including group winners Smart Valentino, Lucy Wires and Destini Fireball.

It was Dyna Willow which claimed her second Wentworth Park staying title. The daughter of Collision was impressive in her narrow victory over Destini Fireball, stopping the clock at 42.48.

The win marked the second victory in two months, following Dyna Willow's Summer Cup win during December.

Representing owner Brendan Wheeler, his parents Paul and Jan, commended trainer Steve Collins on preparation of the multiple group winning stayer, which defeated a classy field in Saturday's run.

Queenslander Benarkin was the best away and set a cracking an early pace, Destini Fireball rounding up the front runner in the home turn, before Dyna Willow lunged on the line to grab victory.

Group staying races returns to Wentworth Park in March with the Betfair Cup, in lead up to the Golden Easter Egg carnival.

Staying races now moves to Perth, with the Group 1 Sky Racing Galaxy.
