Antonio "Sono" Mejia
My Story
In April 2026, I will lace up my running shoes, pin on my race bib, and run 26.2 miles through London. I am running the 2026 TCS London Marathon to raise vital funds for Children with Cancer UK, a charity who's vision is a world where every child and young person survives cancer. Please support me by donating.
I guess this is a good time to open up and be vulnerable about why raising funds for cancer research and care is so important for me. In October of 2025 I ran my first marathon in the Dominican Republic, where I was born. I carried this piece of cloth with 3 women on it. 3 women that shaped my life and help raise me.

They all passed away due to cancer about a decade ago. There's not a day that go by where I don't think of them. It's why I do most things, to make them proud.
Eventually that led me to apply to Memorial Sloan Kettering Cancer Center in 2018 where I worked for years helping cancer patients get treated doing whatever I can to make their treatment a little easier. That work taught me so much and I learned that with the right treatments and care, cancer patients could have a better fighting chance.
With all that being said, this is why I decided to join the Children with Cancer UK team, I wanted to join a charity that meant something to me, to raise the funds necessary to treat this horrible disease in kids that have so much more to live for, so much more to experience from life. Help me raise the funds to do this. Thank you!
