Fans inside the Bird’s Nest stadium could also vote live via We Chat (a Chinese social media channel).
The nine winners of the daily vote were then pooled together for a ‘champion of champions’ vote, which was open from Monday 31 August until Friday 4 September, for fans around the world to vote via the IAAF World Championships, Beijing 2015 page and spikes.iaaf.org
Almaz Ayana’s stunning triumph over her Ethiopian compatriot and 1500m winner Genzebe Dibaba in the 5000m received 23.84% of the overall votes and she wins Performance of the Championships, powered by adidas.
The vote for the top three performances were completed by Ashton Eaton’s decathlon world record on day eight (17.15%) and Dafne Schippers’ championship record 200m run on day seven (14.68%).
Ayana will be invited to the World Athletics Gala in November to receive a special Golden Shoe award from adidas.
