Cooks Classic organiser and van Dalen's former coach Alec McNab has nailed some of the best athletes around to compete in the variety of disciplines on the card on Tuesday night. The headline act for the men's mile is Kiwi Olympic silver medallist and national record holder Nick Willis.
McNab confirmed there will also be three touring groups making Cooks Gardens a stop on their schedule, including Nelson distance runners, an Auckland troop and the members of the Young Olympians tour.
To this, add local prospects such as world junior track and field representative Brad Mathas and runner William Smart.
Leading national javelin thrower Ben Langton Burnell from Palmerston North, who is coached by Wanganui Collegiate's Richard Drabczynski, is also confirmed.
As well as the established names, the average kid off the street in Wanganui will be given a chance to compete under the lights selected from this week's series of Fastest Kids on the Block heats run by McNab.
