Absolutely, and a first class way of getting to understand your new boat. But if you are completely a novice then the overall time needed may depend as much on other factors as Canalplan timings.
Will you have made short trips beforehand, out / back to Stourport, to check everything is running smoothly? And ensured you have all the necessary tools, spares, fuel, food etc on board? Will anyone be accompanying you (as a solo boater you may be quite slow handling lines and dealing with locks etc for the first few days)? Will you be on the move from dawn to dusk, or take it more leisurely? Have you got somewhere in mind to moor when you get to London?
