Story

Thanks for taking the time to visit my JustGiving page.

From my very early days to the age of 17, I was treated at GOSH and wouldn’t be where I am today without the treatment and care I received. Having already completed a couple of Half marathons, 10 and 5ks, I thought it was finally time to do the big one AND it’s the final London Marathon before I turn 30 in January 2027.

I’ll be running multiple charity classes from my work place (PureGym Maidenhead) to help raise as much money as possible as well as asking for donations in general.

Any donations are greatly appreciated and your support will help me stay motivated when taking on the prep for this mammoth task!!

Thank you in advance and I look forward to keeping you all up to date in my marathon training journey.
