Royal Troon is set to have the longest hole in the history of The Open championship when the world's best golfers descend on the links course in July. 

The South Ayrshire course will host the 152nd running of the championship from July 18 to 21. 

The sixth hole on the course is set to measure 623 yards, which is 22 more than it did when Royal Troon last staged the tournament in 2016. 

The course could also play host to the shortest ever hole in Open history, with the eighth hole potentially being reduced to 99 yards for one round by organisers. 

The par-three 'Postage Stamp' hole will measure 123 yards on the scorecard, but the tournament's organisers, the Royal & Ancient Golf Club of St Andrews, wants to shorten the distance. 

This year's event is set to be attended by 250,000 people, a record attendance for The Open at Royal Troon. 

The venue last hosted the championship in 2016, when Henrik Stenson narrowly beat Phil Mickelson to the lift the claret jug.
