Gee, I thought my wife and I play fast (just a little over 3 hours while walking 6500 yard course up and down the hills). The fasted we played was 2 hours and 30 minutes with cart. 1:30 is hard to imagine. Was there anything to the course which made 1:30 pace possible or were you just making hole in ones at will ?
We were both 11 handicaps and we were riding and know how to use a cart properly. We can go from tee to near the green on a typical par 4 in 4 minutes or less. 10 x 4 = 40 minutes. 4 minutes to play a typical par 3 times 4 holes is 16 more. That's 56 minutes. That leaves more than a 1/2 hour to play 4 par 5 holes, putting out and extraneous short delays. When I said just over 1:30, that could have reached 1:45... we weren't really timing the round, we were just surprised when we were back in the restaurant after having finished the round and put our clubs back in our cars, returned the cart, walked up the stairs and ordered a beer and it was still under 2 hours since our tee time.
