It takes time and training to prepare for a 65km walk.
65km is a long way to walk. If you want to make the distance, you will need to train and prepare. A steady pace is around 1km every 10 minutes, or 6km an hour. That means it will take 11 hours to walk the distance. You may easily need 15 hours from start to finish once you add in breaks for the bathroom, food and clothing changes.

Get walking!
There is really only one way to train for a long walk – and that is to walk long distances. Doing this will help prepare the right muscles and get them used to that long slog. Long walks are also an excellent way to make sure that your clothing and kit will not cause you a problem on the day.
Make sure you do a full stretch after each walk you take.
