I was on a similar ride recently, 7 days, 4-5 hours a day or riding.

I took one week completely off the bike right after it, so I could leave my bum to heal a little bit (I was not saddle sore but I was tired to sit on the saddle) but mostly to mentally rest. I ended up taking about 10 days off, and I went for the second-next club ride when I came home.

Do take this time to shop for the next trip!!
