• You don't need to run every day. Take proper time off after a marathon to allow your body to recover. Radcliffe takes two weeks.
• The building blocks of Radcliffe's basic training are short runs - either five 2km runs or six runs of a mile. Then she adds in a long run, which she progressively extends throughout her training.
• If you suffer from stiff calves (as I do), wear knee-high compression socks.
• Training can be mentally harder than the actual race. When you hit a wall in a marathon, recall these "rough spots" from training as evidence you can get through it.
• If you are struggling, use disassociation techniques to take your mind off the pain. Slowly count to 100 three times, which covers a mile (for Radcliffe).
By the time she has finished, she usually feels fine again.
