ONLY a select few athletes have the luxury of going out at the top of their sport and Jessica Ennis-Hill, in just a handful of days, may well become one of them.
The Olympic heptathlon champion from 2012 and twice world champion in 2009 and 2015 has made no secret that she feels she has a maximum of two major championships left in her body.
A world title last summer, 13 months after childbirth, and an astonishing two days of competition in Ratingen in June where she bettered her World Championship-winning score to go second on the world list for 2016, despite a previous Achilles injury, has put Ennis-Hill high in the reckoning to defend her title.
