Any Olympic champion and two-time world champion in a multi-event discipline like the heptathlon must be included on a list of greatest athletes.

Jessica Ennis-Hill is all that, but she is also doubly deserving on a place on this list after winning gold at the 2015 World Championships after giving birth to her son Reggie.

Now 30, the Rio Olympics is likely to be Ennis-Hill's last appearance at the highest level of the biggest stage - enjoy it while you can.
