Whitbread Round the World Race
This is on my short list...
"A test of will, courage and skill against the best (or more accurately, worst) nature has to offer." would be accurate. "The ultimate sailing adventure." would also be accurate.
I've followed these races since the early 70's. This is the Catdaddy of all. I would suspect you would be a changed person if you crossed the finish line.
This is not the America's Cup, where money determines how fast you can make it around a short triangular course.
This is about life...endurance, stamina, will, trust, and brotherhood.
Over Twenty Eight Thousand miles is a hell of a long race. Many things can happen.
This could be, in my opinion, the ultimate test of character. I would do it in a second.
Just my opinion.
Velociman, you might be right about the ultimate test. You would be a changed individual, for certain, if you made it.
I would return, and be crazier than you.
