I did a part of it last year. You need to walk with your tent, you won't reach a lodging site every night. I think the longest stretch without civilization (no village/town to buy food etc) is 5 days. So you also need to manage. your food and water supply.

The app is very helpful for that as it gives you water, food and lodging information on the trail related to your current position (so for instance you can see that in 10km there is a river/water fountain/grocery store etc.)
