The Big Half 2025

Take part in The Big Half and join #TeamKidney on Sunday 7 September.

From the creators of the London Marathon, The Big Half aims to inspire entries from participants from all backgrounds. Much like this event, kidney disease isn’t exclusive – it can affect anyone, at any time.

Are you ready to take on the challenge to help end kidney disease? 

We need to improve the lives of kidney patients, faster. We need breakthroughs in research, sooner. Together, we will fund research to save lives.
