A Kerikeri firefighter hopes to climb the equivalent of the world's tallest building while weighed down with 23kg of firefighting gear and breathing from an air tank.
If Simon Trye succeeds this Sunday he will set another world record to add to one he nailed last year by completing the Kerikeri Half Marathon in full firefighting kit in a time of 3 hr 21 min 41 sec.
Proceeds from Trye's stair-climbing challenge will go to Bald Angels, a charity which helps Northland families in need.
To claim the Guinness World Record Trye only needs to climb 1000 steps but he's aiming for 2909 — the number of steps in Dubai's Burj Khalifa which, at 828m, is the world's tallest man-made structure.
With no buildings in Northland on that scale Trye will instead have to ascend the steps of the three-storey John Butler Centre 71 times. The rules allow him to descend by lift between each climb.
