After each evening session of the championships, which runs from 22-30 August, a panel of experts will put together a shortlist of three athletes deemed to be among the day’s best performers.
The IAAF will then announce the names of the three athletes – who need not be winners or even medallists but nevertheless are competitors who grab the imagination of the experts – through the IAAF website and social media, opening it up to the public to vote via www.iaaf.org and decide a winner.
Each day's winning athletes will then form a final shortlist – the 'champion of champions' shortlist – and voting will take place from Monday 31 August to Friday 4 September.
One athlete will emerge as the overall winner and get the accolade of being the Best Performer of the IAAF World Championships, Beijing 2015 presented by adidas.
The overall winner will be announced on 4 September and will be presented with a special Golden Shoe Award at the IAAF Gala in November.
