Hurdles: Diamond Race 2016
After a successful World Indoor Championships in the winter, Omar McLeod burst onto the outdoor scene with victories in Doha and Shanghai to take a huge early lead in the Diamond Race.
McLeod went on to win Olympic gold, but his Diamond Race campaign peetered out. His unfortunate fall in Monaco saw Orlando Ortega overtake him in the standings, and the Spaniard went on to win all four of the last Diamond Race meetings.
For Ortega, it was surely a cathartic victory after he missed out on the title by the smallest of margins last season.
In the women's 100m hurdles, there was only one name on everybody's lips. Kendra Harrison notched up victories in Eugene and Birmingham to take an early lead in the Diamond Race.
From, there she just kept getting better, winning six out of seven Diamond Race meetings to ease her way into the Diamond League history books and get her hands on a first Diamond Trophy.
Her season was made all the more incredible after she failed to make the USA Olympic team, before breaking the world record at the Müller Anniversary Games in London shortly afterwards.
Eilidh Doyle's victory in Doha gave her a strong start to the 2016 Diamond Race campaign, but it was Janeive Russell who looked like the favourite in the first half of the season after she won in Rome and Rabat.
Doyle hit back with victory in Monaco, and Russell's campaign eventually fell by the wayside, leaving the Scottish athlete to battle with Cassandra Tate for the Diamond Trophy in the final stages of the season.
Come the final in Brussels, Doyle needed only to finish ahead of Tate to secure the title, but the American was up to the challenge, winning in Belgium to take the Diamond Trophy at the very last hurdle.
The men's 400m hurdles, meanwhile, developed into an excellent three-horse race as the season wore on. Michael Tinsley won the opening two rounds, while Javier Culson's consistent finishes within the top two meant that he was never far away from the top of the standings.
It was Kerron Clement, though, who eventually triumphed. After winning his first Diamond Race meeting of the season in London, Clement grabbed Olympic gold in Rio before returning to Europe to secure the Diamond Trophy with a win in Zürich.
