Wiles prepared Mains Power to win the $17,000 Artesian Express class 2 handicap (1200 metres) at the Dirt 'n' Dust weekend at Julia Creek.

It was the second time Wiles had teamed with jockey John Rudd to win the lucrative race.

In a thrilling finish, Mains Power ($13) reeled in the Jay Morris-trained favourite Cheers Browe ($3.20) in the shadows of the post to prevail in the tightest of finishes.

Cheers Browe led everywhere bar the finish line as Mains Power rocketed home in the final 50m to snatch victory.

Wiles said the win was a culmination of strategic planning to take out the richest race in the region, landing $11,050 prizemoney for the winner.

``A lot of planning and thought went into it,'' he said.

``We set her for this race, kept her big and fresh.

``She's a very handy little mare.'' 

Wiles praised the efforts of his foreman Les Criddock and trackwork rider Sophie Norris.

Wiles said Norris had to return to England due to immigration issues but was adamant she would be back to continue helping the stable soon.

Wiles now has a handy record in the Artesian Express with cheap buys.

He bought Remington Steele for $1800 to win the 2008 edition of the race and Mains Power was purchased for only $1500.

The win was no surprise for Rudd who galloped Mains Power on Monday and was pleased with her work. The former Cloncurry jockey has moved to Roma with his children but said he would return to race days in the North West on school holidays.
