The cover photo of this year's annual is of Jessica Ennis-Hill, the 2012 Olympic heptathlon champion, who returned to the top of the podium at the 2015 World Championships in Beijing. The 29-year-old from Sheffield decided to compete at the championships only a month beforehand. As usual the annual is packed full of essential information for the track and field enthusiast, with results from all major championships as well as reports of the World Championships and a look forward to the 2016 Olympic Games in Rio de Janeiro.
