In 2008, Gowing placed third in the 50-54 age group at the Vancouver - his highest accolade at a World Championships, and he also contested the 2009 World Championships, at the Gold Coast.
Gowing, is racing in the 50-54 age group tomorrow, where he hopes to qualify for the worlds once again. But he will be joined by some impressive competition.
"It is great to finally have the old professional's racing in my age group - Rick Wells [former New Zealand Commonwealth Games swimmer], Scott Molena plus Steven Farrell and a few others will put me in my place," Gowing said.
The last time Gowing raced against Wells, who is making a "comeback" to the sport because the World Cup event is being staged in Auckland, was at the New Zealand Triathlon Championships in Auckland in 1984. Wells won in 1 hour 51.29mins, and Gowing clocked in 34 minutes later.
Around 20 triathletes from Northland will head to Auckland for the event, with most aiming to qualify.
"If they don't they will have been part of a triathlon event like they have never experienced before," Gowing said.
The 1.5km swim consists of two 750m laps alongside Queens Wharf. It will be followed by five laps of an 8km cycle course up Queen St and on surrounding CBD roads. The run is four laps of a 2.5km course along the waterfront.
The Northland contingent: Denise Limby, Rachel Edge, Jane Young, Christine Fraser, Sioux Campbell, DJ Gillming, Marion Maxwell, Brent Lewis, Aaron Taitoko, Robert Haynes, Mike Hardiman, Mike Gowing, Graeme McDonald, Chris Seeley, Mike Gillming, Jeff Cook (Also from Northland, living elsewhere Tom Andrews, Simone Ackerman, Nicky Samuels).
