The cover photo of this year's annual is of Sally Pearon, the Australian high hurdler who made the comeback of the year when she won the world 100m hurdles title at the London World Championships. She had won gold at the 2011 World Championships and then in the 2012 London Olympics. But two serious injuries had denied her any more medals until her 2017 triumph. As usual the annual is packed with essential information for the track and field fan, with results from all major championships as well as a reports of the World Championship and a look forward to 2018.
