Completing and training for a half marathon is physically demanding. As a competitor, it is important that you are physically capable of undertaking a challenge of this nature. If you have any medical concerns about participating in the event you must speak to your general practitioner (GP). This advice supplements anything your GP may tell you.
If you get injured or have an illness during your training, do not train until you have fully recovered and then build up gradually. Do not attempt to catch up on lost mileage after illness and injury - this may cause further damage. To reduce injury risk, train on soft surfaces when you can, especially on easy training days. Vary your routes; do not always use the same shoes and run on differing cambers, hills etc.
If you have any known medical condition, please write all medical details on the back of your race number and put a small indelible red cross on the front of your number.
