Fair play to her - the last time I even thought about doing 500km I had to pour myself a stiff drink and go for a lie down in a dark room until the feeling past. And Airborne - I suspect you're right - you wouldn't kick her out of bed, she would kick you out!
But at a time when we are at breaking point, a quick look through RAF Active and no doubt around the various Stn Exped boards and you will notice a common theme of the same branches doing these sorts of things. Sour grapes? Possibly a small bunch if I'm honest - correction, if we're all honest - because these sorts of adventurous things are part of what we joined for. But you do have to ask which Branches and organisations have enough spare capacity to release people for the events which will likely take up a large amount of time in trg and prep when if you believe the politicians and VSOs we are barely keeping the barbarians from the gates.
