You would need rest days.
TBH, you (yeah you personally) have no idea how your body will handle the consecutive punishment. I ride to work and back 5 days a week, 50 miles a day. If I wasn't working, I could do 100miles 5 days a week, easy. I don't think I could do 100miles every day for weeks. Hmm, no, that's wrong. I'm CERTAIN I couldn't do it.
The cummulative wear and tear is huge. You will hit exhaustion levels where you will be weeping at the thought of carrying on.
You may have the sort of physique that means you can do this. However, I doubt you will have the endurance yet. I'm 40 now, and I can ride for longer than I could when I was 20. Slower, but longer.
Try to get in at least one 4-5 hour bike ride every weekend. That will start to build your endurance.
