re: What’s the most holes of golf you have ever played in a single day?

Did the longest day of golf at my home club once growing up. Me and three of the pros tees off at sun up and had free reign to play through everyone on the course. We had lights and sirens on the carts. Basically for every hole played $10 went to charity. You are basically running from cart to ball and back to cart. Played for 14 hours... 253 holes completed. Held the record for the event at the time. Not sure if it is still
