How long does it take _you_ to cycle 401.5 km? A week? Two days? A very long day?

On one hand; these equations are probably useful for the design, and I'm certainly not afraid of math. OTH it feels like an overkill for a one time DIY project; I just wanted to build a bike RV, not retake highschool advanced physics.
