Jessica Ennis-Hill participant in athletics at the 2016 Summer Olympics
2015: Comeback and third world title
Ennis-Hill made her comeback in the Great City Games in Manchester in May, finishing third in the 100 metres hurdles.
 She then finished fourth in her first heptathlon since the London Olympics at the Hypo-Meeting in Götzis, Austria, comfortably achieving the qualifying standard for the 2016 Rio de Janeiro Olympic Games. The competition was won by Canada's Brianne Theisen-Eaton, who set a national record.
After competing in three events at the Anniversary Games at the London Olympic Stadium, Ennis-Hill declared herself fit for the Beijing World Athletics Championships, where she won the heptathlon with a total of 6,669 points, ahead of Theisen-Eaton and Latvia's Laura Ikauniece-Admidina.In July it was announced that a re-test of a blood sample given in 2009 by Tatyana Chernova showed the presence of a prohibited anabolic steroid. The Russian anti-doping agency annulled two years' worth of Chernova's results, but the period of annulment ended 16 days before the 2011 Daegu World Championships, where she won the gold medal. Silver medallist Ennis-Hill appealed to the IAAF that Chernova's results annulment should extend to that competition. In turn the IAAF similarly appealed to the Court of Arbitration for Sport. Ennis-Hill was retrospectively awarded the gold in 2013.In September Ennis-Hill was nominated for the European Athlete of the Year award, which was won by Dutch sprinter Dafne Schippers. In November Ennis-Hill won the Sunday Times and Sky Sports Sportswoman of the Year award for a second time, was voted BAWA Athlete of the Year for a record equalling fifth time (tied with Paula Radcliffe), and was nominated for IAAF Athlete of the Year. In December Ennis-Hill was selected as SJA Sportswoman of the Year for a joint-record fourth time (again tied with Radcliffe), and was voted the best British and International Female Athlete in 2015 by the Athletics Weekly readers. She also finished third in the 2015 BBC Sports Personality of the Year, behind Rugby League player Kevin Sinfield and winner Andy Murray. It was the fourth time she had been voted in the top three of the award.
