“If it keeps presenting itself, there is a reason,” she said.
“It is always nice to go with someone you know and we live together, so we can manage.
“When you are getting out of our comfort zone, it is always a growing experience.”
Suze said while they were fit, they could not be fully prepared for the trek.
“We are going to learn about a new culture and we do not know who we will be travelling with; there is meant to be eight people in our group,” she said.
“It will be physically and mentally challenging because when you are on the way up, you cannot come back; you can but you do not want to be doing that.”
Tekaisha said she was excited to experience the “once-in-a-lifetime” trip.
“The goal is to make it to base camp; it is 5.5km straight up,” she said.
“The biggest challenge is the climate because no matter how fit you are, it will get to you anyway.”
Tekaisha said she was keen to do something extreme again, while Suze said she would do one thing at a time.
