Katie Noblett was just 10 when her mum was diagnosed with Multiple Sclerosis.

And, while she was too young to really grasp how the disease would affect her mum, Lianne Knowles’ life, Katie soon stepped up to become her carer.

Katie, who is now 22, said: “My mum was only 39 when she was diagnosed with MS. As my dad worked away throughout the week I became her carer for the time he was away."

Never questioning her role, Katie received a lot of help and support from the MS Society which funds research into treatment for the condition that is a chronic autoimmune disease of the central nervous system (brain and spinal cord).

And now Katie wants to repay that help by running in the London Marathon to raise money for the society.

She said: “I wanted to also raise awareness of the charity and the work it does to help other people like my wonderful mum who has faced so many challenges.”

And while fitness is Katie’s speciality, as she runs the gym at Burnley College, where she also teaches sports science to students after gaining her degree and PGCE, a marathon is way out of her comfort zone.

She added: “I usually take part in HYROX, a global indoor fitness race combining 8k of running with workout stations. I’ve been in training for 16 weeks and it’s been tough.”

Katie will be cheered on by her boyfriend, Cory Ince, and her best friend Niamh Hutchinson in London on Sunday, April 26. And her mum will be watching the event on TV at home. To donate to Katie’s challenge please click HERE
