The 13th episode of this season's IAAF Inside Athletics is available to watch online now and features an exclusive interview with US sprinter Phyllis Francis.

Phyllis Francis was crowned world 400m champion in London earlier this year, but looking back on her career she believes another key moment came at the 2016 US Olympic Trials when she achieved her maiden sub-50-second clocking over the one-lap distance.

The headlines after the IAAF World Championships London 2017 women’s 400m focused in tone more on two of the women who finished behind Phyllis Francis than the actual winner herself.

US 400m sprinters Phyllis Francis and Josephus Lyles were in the spotlight at the International Meeting Sport e Solidarietà in the Italian seaside resort of Lignano Sabbiadoro on Wednesday (12).

With just the top two advancing automatically per heat, plus the next eight fastest across the eight heats, there was little margin for error but all the main contenders could say: “mission accomplished”.

USA could have taken it easy in the heats of the women’s 4x400m at the IAAF/BTC World Relays, Bahamas 2015 as they looked to defend their title from last year.

Sanya Richards-Ross and Allyson Felix are set to go head-to-head over one lap of the track at the IAAF Diamond League meeting in Eugene on 30 May, after the meeting organisers announced their women’s 400m field on Wednesday (29).

Kendell Williams smashed the world indoor junior record* in the pentathlon to provide the highlight the NCAA Indoor Track & Field Championships in Albuquerque, New Mexico on Saturday (15).
