Great idea, Dennis. This is something I intended to do this past summer but didn't have a chance to. It's a great way to stay in shape for an unexpected repeat journey under more strained conditions, both physically and mentally.

In tandem with Montanero's suggestion to consider alternate routes, I'd also run through a few scenarios in your mind about when and I why you'd take those routes. They may inform your Plans B and C.

Well done and thanks for the inspiration!
