The Cromwell man will finish a fruitful year by representing his country at the Australasian Cherry Pip Spitting Championships next week at Manjimup, Western Australia.
''My training regime has been ... rigorous ... swimming, cycling, and more,'' he said, before dissolving into laughter.
A spit of 11.5m at the national cherry stone-spitting championships in Cromwell in January gained him the right to test his skills at the Australasian contest, being held on December 14.
''I'm really looking forward to it and I'm going to have a good crack at it,'' he said.
Jacksons Orchard, at Cromwell, generously provides cherries for his training as well as providing the fruit for the national championships, which will be staged in the Cromwell mall on January 4.
It will be the eighth year Cromwell has hosted the event, while the Manjimup cherry festival and championship is in its 12th year.
The nationals were Mr Wardill's first attempt at competitive cherry stone-spitting, but he was reasonably confident he could go the distance.
''You know what it's like when the boys get together over Christmas and there's cherries around ... of course you see how far you can spit the pips.''
Getting the stone properly positioned in your mouth was one of the key skills - ''you have to make sure your false teeth don't fly out as well,'' he joked.
''Everyone has their own technique; I'm sure there's a million different techniques.''
His son Bob (13) will be going with him to Australia.
Bob was placed second in the junior section of the national championships - obviously he is a pip off the old block.
