How fit are you? A normal healthy person can ride 70-100km in a day. I think you can do it in 2-3 days

You may want to consider to purchase a pair of slick tires since I assume you use original knobby tires. Once you change to narrower and slicker tires, you can feel the difference!

If you have horizontal dropouts or track forkends you don't need a tensioner
