Medical support is provided by KLP Medics, and checkpoints are stocked with drinks, gels and other high energy items to support refuelling needs. The organisers note that route accuracy is subject to the nature of the Thames Path trail and public use.

  • Half marathon: one 13.1 mile out and back to opposite Barnes Sports Club.
  • Marathon: two 13.1 mile out and back laps to opposite Barnes Sports Club.
