Hello Everyone,

Welcome to my page!

In 2025 I did the London 10k run in helping raise money for a disabled charity that helped support my disabled twin brothers and raised an amazing £5,000!

But this year is a little different. In the early months of 2026 I lost a very close friend to myself and it has not felt real since. James Macfarlane was a true gentlemen to anyone he crossed paths with and id do anything just to hear one of his terrible jokes or an inspirational story he had!

This year me and Dorota will be doing the London 10k again in memory of James and money raised will go to his absouletly amazing daughter Lillith.

Thank you for reading and helping with my goal and journey ❤️

Lots of love

Jack Costin and Dorota Marzec - Barczak
