A Northwich woman is braving temperatures of minus 30 to take part in a race known as the Arctic Ultra.
Hayley White is in Canada to compete in the 380 mile race on foot (totally self supported/carrying a pulk) for 9 days.
She is the only female from Great Britain among the 15 athletes taking part.
As part of her training, she spent two days of learning survival, in the Breacon Beacons learning how to use your kit in sleep deprived conditions and just how your body starts to react to the extreme conditions that occur in the Arctic.
Minus 30 and wind speeds of up to 70mph isn't uncommon.
Hayley is raising funds for Mind and she said: "As a medical exercise personal trainer, I have over the last 17 years met, and dealt with clients suffering with different degrees of mental health, depression and anxiety.
For many its overwhelming and sucks life, fun and everyday joy out of you and has a catalogue of consequences for them and their family/closest friends.
"I have sadly, in 2018 alone, lost two clients and a friend to mental health and depression. Trying to explain to my 9-year-old son that his rugby coach sadly passed away is something no one should ever have to do and especially when his condition was not identified."
