"They're heavy-duty trampers," Mr Mackie said. "The biggest problem they'll face is altitude sickness." One of Mrs Mackie's fellow trekkers, Jenny Burns, had been unable to reach Base Camp due to altitude sickness, and Mrs Mackie had suffered from altitude sickness herself, Mr Mackie said.
Although it was their first time at Base Camp the party could draw on a wealth of tramping experience. Only last month they had been trekking in Mount Aspiring National Park in the South Island and Mrs Mackie was a member of Search and Rescue New Zealand.
Mr Mackie didn't quite share his wife's zest for climbing. "I'm a pilot. I fly airplanes because it's quicker and I don't have to carry a load," he said.
Mrs Mackie hoped this week to visit schools involved in the Classrooms in the Clouds project, which built classrooms in the rural areas of the Everest region of Nepal. The trekkers had brought stationery supplies from New Zealand to donate to the classrooms, thanks to support from Warehouse Stationery.
"I daresay this won't be the last time she takes on a challenge like this."
Mrs Mackie was due to return to their Puketiri Rd lifestyle block on May 3. "I miss her terribly," Mr Mackie said.
