When I read about The Big Hike I knew this was the perfect challenge. The day was so poignant and yet brilliant too. Just to be out in breath-taking countryside surrounded by everyone who loved Adrian and June was incredible. I’d thoroughly recommend it to anyone who is thinking of doing it this year.
For those of us who took part, it was the ideal way of honouring them both and to help do our bit to help fund life-saving research.
Catherine and 11 family members took part in the Big Hike challenge in 2023. They hiked in memory of her husband Adrian, who died from bowel cancer, and his mother June, who died from lung cancer.
