Well done that woman. But I married one like that too. Not a soldier but this weekend my wife completed a marathon. She didn't run but walked the distance and even got lost twice. She made it in just under seven hours. She had the absolute minimum of training but she did it. I'm very proud of her. She's only a little woman, five foot nothing but determined with it. Never underestimate a woman.
I'm not surprised though, she once trekked to Everest base camp.
Having said that she's been in agony the last two days. She's tougher than me though.
