I'm running the London Marathon for Princess Alice Hospice in memory of my mum, who passed away this March after a four year battle with cancer. The amazing team at Princess Alice were instrumental in organising and providing her care, especially in the last few weeks, and we wouldn't have coped without them.

I remember watching her fight through the miles to run her best marathon time (3:33:35) at London in 2012 - and thinking I would never want to put myself through that - so naturally my goal is to get as close to her time as possible.
