Golf fans usually see caddies for about ten seconds a broadcast, standing off to the side while a player reads a putt worth a trophy. That’s the highlight reel version. Nobody airs the four days before it, the walking, the note-taking, the muttered disagreements over which club actually plays right on a breezy par three. By the time the cameras show up on Thursday, the real work is already mostly done, and the caddie has usually been on site longer than anyone else in the group.
Monday Starts the Real Work
Monday rarely feels like a day off, even though nothing official has started yet. Registration needs handling, bags need unpacking, and if a player wants something adjusted, that’s a walk over to the equipment trailer before lunch. Quite a few caddies also slip out onto the empty course that afternoon, before their player has even checked into the hotel, just to shake the rust off their memory of where everything sits.
Anyone who’s looped a tournament before tends to pull last year’s yardage book off the shelf and start comparing it line by line. Courses move around more than people think. A tee box gets pushed back ten yards, the rough grows in thicker on fourteen, a fairway bunker gets reshaped over the winter. Small stuff, sure, but it adds up fast once real scores are being posted.
Walking Every Inch of the Course
Tuesday and Wednesday are where things get serious. Practice rounds aren’t really practice for caddies so much as an audit. Every hole gets walked, often more than once, yardages checked against sprinkler heads, elevation changes double-checked so nothing gets fudged once the round actually counts for something.
Elevation is the sneaky one. A downhill approach that plays two clubs shorter, or an uphill tee shot that quietly eats an extra club’s worth of distance, can cost a player strokes if nobody flagged it in advance. That’s why the veterans treat those practice days almost like inspection work, running the same numbers twice before trusting them under pressure.
Trouble spots get marked down too, the kind that don’t show up on any printed map. A bunker tucked just out of sight off the tee. A green that slopes harder than it looks on television. A corner of the property where the wind seems to swirl for no good reason at all.
The Yardage Book Becomes the Bible
By Wednesday night, that yardage book barely resembles what got handed out at the registration desk on Monday. What starts as a generic tournament printout ends up layered with personal shorthand, green contours, favorite landing spots, little reminders about how a certain pin location played the last time it showed up.
Since 2022, the PGA TOUR has required these books to meet committee-approved standards, mostly to pull back on the ultra-detailed, laser-measured green reading books that had started creeping into the game. Even with that rule in place, the yardage book is still the one thing caddies trust more than almost anything else out there, and it rarely leaves a back pocket, practice round or not.
Daily pin sheets feed straight into all of this. Every morning, the day’s hole locations get copied into the book by hand, so the strategy that gets built is based on exactly where the flag sits that day, not some rough guess left over from habit.
Building the Game Plan Together
Knowing a golf course cold doesn’t win anything by itself. That knowledge only really matters once it turns into a conversation between two people who trust each other. Before the tournament starts, and usually again before every round after that, caddie and player sit down and talk through the layout hole by hole, deciding where it’s worth taking a run at the flag and where laying up is the smarter play.
Distance is just one piece of that talk. Wind, how the player’s swing has looked that week, even where things stand on the leaderboard, all of it gets weighed. A caddie who’s put in three straight days of legwork walks into that conversation with something real to say, not just a guess dressed up to sound confident.
Equipment, Routine, and Rest
None of this is only mental, either. Grips get wiped down, clubs get checked over, and anything that needs fixing gets handled at the equipment trailer well before tee time. A short warm-up usually follows, some putting, a bit of chipping, the same routine most days leading into the event.
Rest matters just as much as any of it. This job is genuinely rough on the body. Caddies typically cover five to six miles a round carrying a bag that can weigh anywhere from thirty-five to fifty pounds, and across four competitive rounds that stacks up to more than twenty miles, without even counting the extra ground burned during practice days. Staying fresh isn’t a luxury here. A worn-down caddie on Sunday afternoon isn’t much help to anybody.
Parting Shot
There’s a lot more happening before Thursday’s first tee shot than most fans ever stop to think about. By the time competition actually begins, a caddie has already put in miles of walking, filled a notebook with hard numbers, and worked out a real plan alongside the player carrying the clubs. That quiet, unseen effort is exactly what shows up later as a calm word and a steady hand when the tournament gets tight, and it actually matters.
