Yeah, good.
Nothing like the straps digging into your shoulders...head out like a turtle and your back bent.
If you don't look like that you ain't carrying shit lol.
I remember completing the 12 mile ruck during Phase I in about 2 hours and 40 minutes. I also remember that there were guys who jogged the entire distance and finished in a little over two hours. If I tried anything like that now I'd probably have a heart attack.
