Qualifying swims must be conducted in water that is 16 degrees Celsius or less, and in the same swimming suit that you will use for your Channel swim. Relay swimmers must finish a 2-hour swim, while solo swimmers must complete a 6-hour swim. Once you've finished your qualifying swim, send proof to the Hon. Secretary, Kevin Murphy. He will then send it to the Chief Commissioner of the ISSF, who will decide whether you have fulfilled the conditions necessary to be allowed to attempt the swim. The channel crossing itself must be done within 24 hours of completing your qualifying swim. You must submit a medical certificate from your doctor before you can begin training for the swim. The doctor's certificate should say that you are in good health and not under any special medical supervision. It also needs to say that you are in no way hindered by any physical defect or disability and that there are no psychological reasons why you should not take part in this type of swim. Finally, you must provide proof that you have complied with all these requirements. This may include evidence such as photos or videos taken during the qualifying swim or after the crossing. These must be sent to the Hon. Secretary at kevin@issf.com. You will need to pay a fee of £10,000 to enter into the record book. This must be done before you can start training for the swim.
