Why take part with Cancer Research UK?

Meet Rika

My favourite moment was the Cancer Research UK cheer point, where my beautiful daughter and incredible husband were cheering me on!

- Rika

Rika joined our team UK in 2025, running in memory of her Mum.

"I relied on Cancer Research UK to learn more about breast cancer when my mum was diagnosed. Educating myself was a productive way to try and process everything. I eventually lost my mum to breast cancer in March 2020. It was a no brainer when it came to choosing a charity to raise money for. My mum was a gym bunny, so I thought she’d find it funny that I was going to be running in her memory. I enjoyed every single mile."
