Human Factors
Upon landing on Runway XXR; we were given taxi instructions to the maintenance hangar via E; U; V; C; cross Runway XXL. As we reached Taxiway V on U; I saw the red and white XXL-YYR sign to my right and made a right hand turn and inadvertently crossed onto Runway ZZ-WW before I realized I had made a wrong turn. The Tower called us on our mistake and re-cleared us around the north side of the airport to the hangar.It was a difficult day due to weather; maintenance; a ferry flight and a diversion before getting to [destination]. After the diversion; it was a quick easy flight to our destination. Once on the ground it felt like we were finally 'done;' just a short taxi to the hangar. Upon making the turn onto Taxiway U; I saw the XXL-YYR sign and I needed to cross it; looking right past the Runway ZZ-WW signs and rolling onto that runway. Thankfully Runway ZZ-WW was not in use at the time. Looking back; what I did made no sense; that route is way out of the way. I was concerned about crossing that runway not where to cross it. I need to double check the airport diagram and ask myself is this right? After landing; I let my guard down; we were 'DONE;' 'It's easy from here.' I need to make sure we're not done until we're parked and off the plane.
