in selection it was min 55 lbs - no food or water. until we got to the "trek" where it was 75 lbs w/ no food or water. not really sure about the distances. they don't tell you anything except go as fast as fast as you can. we had 3 timed runs about 5mi, 7mi, and 9mi. 3 timed ruck marches 8mi, 12mi, ~15mi. those where not that bad - it was the 13 hrs of land nav a day for the next 3 weeks that sucked. last evolution was called "the trek". had 48 hrs to go about 65-70 mi. thing is your broke and busted down buy that point so it's a kick in the balls. and it will only get worse - phase 2 for us was even more torture. lost ~30 lbs at selection - sucked had to work my ass off to put it back on. you'll loose even more a ranger school though. work on endurance. are those you #'s in your sig? what is your weight?
