Chewin in the Chung

Surely, we've all thought about running away and joining the French Foreign Legion. You can run away from criminal records, bad marriages, poverty... I'm not sure what you do when it's time to run away from the French Foreign Legion.

So, I'm going through that site, and hit the part "Appraise your physical condition". OK, let's do it.
1) 30 pushups: Check. Did this at the gym just a few months ago.
2) 50 situps: No prob. Hell my wife can do 50 situps.
3) Climb a 20 foot rope without using your feet: Uh oh. How do they measure this? Cause if I can jump up and grab the rope, then I've only got to climb about 9 feet. But I haven't tried to climb a rope in years. Sounds tough.
4) Run 8 kilometres with a 12 kilogram rucksack in less than one hour: Not sure about this either. 8 kliks is 5 miles, 12 kg is 26 pounds. Should be doable, I guess. Does the rucksack bounce around?
5) 8 chinups with your palms away from you as you grip the bar: Problem. I think I can do three. Better start working on this.
