New user,

read this post in my RSS feed and couldn't help but add some insights.

I have completed a 22-25 mile in what I believe was around 7 hours. I ran about 50% of the time, and carried 65-70 pounds dry (without water), over unimproved roads, and limited cross country (low vegetation). All I remember is I left at midnight and arrived at the destination just after full day break.

US Army infantry standard is 12 miles in 3 hours with around 35-40 pounds. Most will have to run a little, or at least full hard striding the whole way.

4 miles an hour with hardened troops is a reasonable pace to arrive at the destination in fighting shape. However, the aforementioned 22 mile march left me unable to do much for a day or so at completion.

Average patrolling speed for a deliberate foot patrol is 1 kilometer an hour cross country. This speed is planned when the element is moving slowly and deliberately.

Full cross country I have completed 20 kilometers in rough terrain, vegetation, and water crossings, in about 10 hours.
