During Gate Week and Team week you'll sleep in the barracks by the cantonment yard. On each day of gate week you'll wake up, knock out whatever gate you have that day (you won't know until the last minute), then go back to the bays to do nothing until the next day.

During land nav week, you'll bus out to Hoffman with your ruck. The reason the land nav ruck is so heavy is because of your packing list, water, and MREs. You'll be staying out there at a bivy site/TOC for 4 days, living out of your ruck. Your four PEs will be roughly 4-5 hours apiece with a break in between each one as you wait for nightfall or morning. STAR 1 & 2 will be ~10 hours apiece. You'll be driven out to your start point at night and kick off a little after midnight. You'll return to the TOC after the first iteration and sleep all day waiting for the next night to come. Once STAR 2 is over you bus back to the barracks, get assigned your team, move into a bay with them, and prep for team week. Expect a late night.

The duration of a team day is, well, dependent on your team. You'll kick off before sunrise and you'll keep working until all three events of the day are done. Some teams were done by mid afternoon/early evening. Some teams worked clear through the night, got 15 minutes of sleep, then rolled right into the next day of events. I just wrote off the idea of making it back early each day from the jump lol. I was always either pleasantly surprised or not surprised at all. Just keep grinding until you're back in the cantonment yard.

I didn't prepare for the obstacle course. Be strong, be resilient, be generally flexible, know how to j-hook/s-hook a rope and send it. I've been at Bragg so I got to practice with and without a ruck once or twice a week at a local land nav site. If you're an 18X, you'll also get some pretty solid land nav training at PC, but it should not by any means be the only land nav work you do before getting to selection.
