As another year comes to a close, europeantour.com has had the calculator and the scorecards out to bring you this – a definitive guide to the 18 most testing, challenging, terrifying holes in the 2017 Race to Dubai.

We have crunched all the numbers from last season to identify a complete golf course’s worth of what are technically the hardest holes on the European Tour.

Last year, it was the par four 18th at Carnoustie which took the crown as the most difficult hole on Tour, but what hole will claim the same honour in 2017?
