The 148th Open Championship gets under way on Thursday morning with homegrown favourite Darren Clarke hitting the opening shot of the tournament at 6.35am.
It will be the first of four days of intense action on the famous Dunluce Links.
Around 200,000 fans are expected to descend on Royal Portrush, with millions more watching the action unfold on TV.
