Karen and Matt share their fitness stories

Karen - "I use exercise to help me mend my broken brain and body"

Karen's endometrial cancer diagnosis took a detrimental impact on her day to day life and wellbeing. It came at a time when she was dealing with other health issues and grieving. After talking to her Macmillan Buddy, Karen started making changes to her life to improve her wellbeing, pursuing exercise that worked for her. 


"It has become a medicine for me and given me sunshine and new hope. I go to the gym to exercise and to have coffee and a natter with others. I know I will never be 100% but I am not just a person with cancer. Exercise reminds me I have a purpose."

Matt - "I couldn't imagine not running, everyone knows me as a runner, it’s part of my identity"

At 28, Matt was shocked by his thyroid cancer diagnosis. Going through treatment was a life-changing process for him. He began to feel like a party of his identity was missing because before his cancer diagnosis he was an avid runner. As he went through treatment, Matt found companions and support through one of Macmillan's Cancer Support Centres. But, at the recovery stage, Matt couldn't ignore the benefits running bought him...


"I was in hospital for 5 to 6 days, then I put my feet up but 25 days later I ran a 5K. I don’t know how, don’t ask me! A week later I did a 10K, then the Great South Run which is 10 miles the next week... All for charity. It gave me that goal and something to focus on. It gave me that resilience that I won’t let this stop me."
