Catherine and 11 family members took part in Big Hike in 2023, hiking in memory of her husband Adrian and his mother June:

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 breathtaking 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.
