How long does a round of golf take? Too long!!! Well with 4 players in a charity event my record was 5hrs 45mins, this is not a good record. Would have stop after 9 if it wasn't for charity. Turned out to be a really good day but woukd have been even better with a sensible amount of time on the course.
The PGA Championship tournament is 72 holes long and begins with a field of 156 golfers. At the midway point - after 36 holes - that starting field is reduced (or cut) by roughly half. The golfers with the low 70 scores, plus any ties, make the 36-hole cut and play the final two rounds.
