What is the TCS London Marathon like? 

Picture this. 40,000 runners and spectators all coming together, creating an atmosphere like no other. And you could be part of it.  

Take on the 2025 TCS London Marathon with us next April and help support children and young people live happier and healthier lives.

Barnardo’s supported me from start to finish and shared my excitement throughout! I learned so much about the wonderful work they do to support children and families which was highly inspirational on the day! I was very happy to support such an amazing charity.
