Kayon Raynor assesses Bolt's decision to extend his career beyond the Rio Olympics after the Jamaican announced his intention to compete at the 2017 World Championships in London.

The 8-time World Championship gold medallist has said his "sponsors asked him to continue", our reporter in Kingston believes Bolt may be eyeing up the record of 14 World Championship Medals.

Despite being 31-years-old in 2017 Raynor expects that the sprinters' focus on just one race should make the 100 metres "easy pickings for the best track and field athlete of all time" and that his year out with injury last season could help due to "one year's less wear and tear on his body".
