In two weeks’ time, runners from around the world will compete at the IAAF/Cardiff University World Half Marathon Championships Cardiff 2016 on 26 March.
The championships will be returning to the country that hosted the first edition in 1992. During the 24 years that has passed since then, the essence of the event – a celebration of the world’s best road runners – has remained constant.
But there have also been some changes along the way, as shown by these selected highlights.
