I'm gonna go cycling for a week with just a tent and the essentials. Planning on riding for 3 days, taking a one day break, and then riding back for the last 3 days. Pitching a tent in the woods or wherever I find. I haven't done anything like this before and I haven't even been camping since I was a kid. Is there anything I need to/should know that might not have occured to a novice like myself? I'm gonna be alone for the whole week and possibly in a foreign country so I need to be 100% independent

pic related is the area I will be cycling in (mostly plains and forest). I'm planning on covering about 100km/60mi a day (yes I'm sure I'm capable of that)
