Before you undertake any physical activity, it's a good idea to prepare yourself for it physically and mentally. Athletes perform warm up and stretching excercises before competing and mentally see themselves crossing the finish line in first place. You need to do the same.

Training ensures you are physically prepared, able to complete the adventure safely and will also greatly contribute to your enjoyment of the event.  You should aim to increase your fitness levels to prepare yourself for your adventure of a lifetime!

Before you start on any training programme, it is always a good idea to consult with your doctor. It would be a good idea to let them know what it is you are planning and they can advise you.
