Kidney disease ends here.


The Big Half

The Big Half

The Big Half will see 20,000 runners start at Tower Bridge before heading through the London boroughs of Southwark, Tower Hamlets and Lewisham, finishing at the Cutty Sark in Greenwich.

Run all over kidney disease!

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.

Run The Big Half and fund research that will save and change lives. But be quick, our places are limited!
