• Live: Texas Relays 2016

Nine of this season's 11 IAAF World Indoor Tour titles will be up for grabs when the six-meeting series concludes with the PSD Bank Meeting in Dusseldorf on Wednesday (20) night, but none will be as eagerly anticipated and as closely watched as the battle for the men's 1500m when Samuel Tefera returns to the track just four days after his sensational world record-breaking run in Birmingham.

Olympic 800m champion Caster Semenya's appeal against a regulation restricting testosterone levels in female runners began on Monday - as the head of world athletics again defended the rule. South African Semenya, 28, is seeking to overturn the regulation at the Court of Arbitration for Sport (Cas). The case will be heard until Friday, with a verdict expected by 29 March.

Richard Kilty, the double reigning European 60m champion, has hit out at not being given the chance to attempt a historic hat-trick in Glasgow after British Athletics were forced into humiliatingly selecting just one male sprinter despite having three spots to fill. 

Ethiopians Ayana Tsedat and Guteni Shone grabbed convincing victories at the 35th Zurich Maratón de Sevilla. 22-year-old Tsedat clocked 2:06:36 to improve the race record by 1:07. Likewise Shone’s winning time of 2:24:29 broke the course record by a similar difference, 1:06. Volha Mazuronak of Belarus  (2:26:13) and Kenyan Barnabas Kiptum (2:09:20) broke course records at the Standard Chartered Hong Kong Marathon.
