Treend also qualified for a solo race in his 65-69 age group which will be the second time he’s attended a Hyrox world championship after competing in Chicago last year.
Costello, who owns The Shred Waipu Gym where Treend is a member, said it was a “fantastic opportunity”.
“I’m looking forward to racing with Mick and being part of the atmosphere.
“There’ll be thousands of people going, the best in the world will be competing.
“The community is right behind it, which is awesome.”
Hyrox is a relatively new fitness racing event which combines 8km of running with eight functional workout stations for professional athletes to everyday gym-goers.
It involves eight 1km runs interspersed with eight functional workout stations, including a 1000m stint on the SkiErg, the sled push and pull, burpee broad jumps and a 1000m row.
There are also 100m lunges with a sandbag on your back, the “farmer’s carry” with kettlebells, and wall balls, which involve full squats and throwing a medicine ball at a wall.
Each race is hosted indoors, so spectators can encourage participants, who start at varying times and finish at their own pace.

Warren, who trains at The Fitness Lab in Kerikeri, also won the men’s open doubles with another partner, Andrew Hope from Kerikeri.
He said he was “stoked” to qualify.
“We put in a lot of training and it’s quite intense so it’s cool to have the training come to fruition and get that result.
“A few Aussies had flown over to get the spot, so it was cool to beat them as well.”
Warren has previously encouraged his parents to get into the sport.
As a result, Bob and Sophia Warren entered competitions in Auckland and Brisbane, which qualified them for the Hyrox World Championships in the United States.
The Kerikeri couple are now the first over-70s mixed doubles world champions after their win at the event at Navy Pier in Chicago last June.
The Waipu community is now rallying behind Costello and Treend with a community fundraiser workout on May 9 at The Shred gym.
A Givealittle page has been created to help get the pair to the world champs.
