When most Kiwi dads race their kids up the driveway it's likely to involve a skateboard, Jandals and a quick visit to the emergency doc - but the Millens do things a bit differently.
Motorsport veteran Rod Millen - winner of numerous motorsport titles and record holder at the legendary Pikes Peak International Hillclimb for many years - is running a race this weekend at his Coromandel property in which all manner of machinery will be going for gold up a mile-long drive purpose-built for fast fun.
Pit Rod against son Rhys - Dukes of Hazzard stuntman, drift champ and Pikes Peak campaigner - and occasional racer, youngest son Ryan, and there's always rivalry. But, in hundreds of thousands of dollars' worth of machinery, it's a far cry from the typical Kiwi game of backyard cricket.
For his 60th birthday last year, Millen invited a lucky few to compete, and quite a few more to watch, as his labour-of-love drive was christened with two days of racing called the Leadfoot Festival.
Everything from Millen's incredible 900hp Pikes Peak Celica to V8 Escorts, rare Porsche race cars and some classic 50s single seaters took a run up the hill.
