The course I play, Braid Hills in Edinburgh, has back to back par fives. The 10th at 549 yards and the 11th at 522 yards. Although due to the prevailing wind I often think the 11th plays like more of a long par 4. Both play in the same direction.
Another course in the Edinburgh area that has back to back par 5’s is Kings acre, where holes 2 and 3 are par 5’s. One a short par 5 of 450, usually into a strong wind and the other running back in the opposite direction at 554 yards.
With regards to the braids I often think it would be better if the longer holes were more spread throughout the routing. As most of the par 4’s are on the short side, bar hole 5 (518 yards) and Hole 6 (430 yards all the way up hill into the wind). Actually hole 6 normally plays longer than hole 5. As five is downhill and downwind and can be as little as driver wedge in the right conditions.
So this means that the long holes come in two little bunches meaning you play long stretches of shorter holes wanting to play something a little longer, to add to the verity of shots required. Would having them apart improve this? Although if these are the holes that were the best fit for the land it would not however be preferable to make contrived holes elsewhere to please the feeling the longer holes should have been more separated in the routing.
