Ahead of the first round today McIlroy says he has to try and win gold at the Rio Olympics – as he's not certain golf will be included at the Games past Tokyo in 2020.
The sport is back on the programme for the first time since 1904.
But some top golfers have ruled themselves out, like Adam Scott, who says it's an “exhibition” event.
McIlroy says winning gold could end up being a career highlight.
