3 Putt Bogey is a golf podcast hosted by Chuck Bryant and Adam Pranica, two mid handicappers who are just good enough to know exactly how bad they still are. The name says it all: one great shot, followed immediately by the kind of self-inflicted disaster only a mid-handicap golfer can produce. That's the whole sport, really, and this show lives in that gap.

Every week, Chuck and Adam break down their most recent rounds, dig through the bag, and try to actually get better — which is harder than it sounds when social media serves up an endless, contradictory firehose of tips, drills, and gear you're told you absolutely need. They'll talk about what's actually working, what's total crap, and what happened when they tried it on the course anyway.

Expect gear talk, course recaps, golf movies and video games, rules debates, questionable gambling picks, and a healthy amount of self-inflicted misery, all in service of two guys trying to shave a few strokes off their game and laugh about it along the way.
