The Thames Path follows England's best-known river for 184 miles (294km) as it meanders from its source in the Cotswolds through to the bustle of the City of London and the Thames Barrier. You can choose one of three distances: 25km, 50km or 100km. And you can choose whether to walk it, jog it or run it!

About the Thames Path Challenge

  • 2nd 25km: Hurst Park to Runnymede – walk only
  • 3rd 25km: Runnymede to Cookham – walk or run

For the 100km, you can challenge yourself to a 24 hour walk or ultra marathon run/jog:

You can also take on the 100km as a 4 x 25km relay team.
