A lot has happened in the 14 years since Tianna Bartoletta won the world long jump title as a teenager.
As we continue our countdown to the start of the IAAF World Athletics Championships Doha 2019, we identify five dramatic moments which lit up the final round from previous editions of IAAF World Championships.
Olympic gold medallists Tianna Bartoletta, Ekaterini Stefanidi and Greg Rutherford are among a host of athletes who have confirmed they will compete at the Müller Indoor Grand Prix Glasgow, the final stop of the IAAF World Indoor Tour, on Sunday 25 February.
Thirty-five podium finishers from Rio, including 11 gold medallists, and 10 world champions will compete at the Müller Anniversary Games on 9 July in what could be their final IAAF Diamond League appearance before the IAAF World Championships London 2017 in the same stadium one month later.
The Oslo Bislett Games got the result it wanted on Thursday (15) as the U20 Dream Mile went like a dream for home runner Jakob Ingebrigtsen. But the IAAF Diamond League meeting also got the result it never really expected as decathlete-turned-400m hurdler Karsten Warholm defeated a field including the Olympic champion Kerron Clement.
US champion English Gardner and Olympic long jump champion Tianna Bartoletta will lead the women's 100m field at the Prefontaine Classic in Eugene on 27 May, the third stop of the 2017 IAAF Diamond League series.
Rio Olympic champions Thomas Rohler of Germany and Tianna Bartoletta of the US are among the first star names confirmed by organisers of Golden Grand Prix 2017 in Kawasaki, Japan, the season's second IAAF World Challenge meeting, on 21 May.
The Prefontaine Classic long jump field includes the three Olympic medallists from last year as they clash once again at the IAAF Diamond League meeting in Eugene on 26 May.
