"It will be a good challenge, it's a big thank you to those who have fought for us," he said.
Mr Osborne said he had been doing the annual run for five years now, but this was only the second year it had been at the Sky Tower.
He said it was great to see firefighters from different brigades - as far as New York - come together and remember the fallen fighters.
Chief firefighter Fancis Boag said he was proud of the four from his squad who were going to the memorial.
"The fact that they do it every year is incredible, they are a credit to the organisation. We have a really good report with our New York comrades. It's a special occasion for any firefighter world wide."
Mr Wallbridge said it was his first time doing the memorial run.
"I wanted to do it so I could represent the Ngongotaha Brigade and to remember those who have fallen around the world, the people who have sacrificed their lives for others."
The four men will be joined by firefighters from all over the country as well as some from New York for the memorial run on September 11 at 3pm.
