American Allyson Felix justified her step-up to the 400 metres with a convincing gold-medal run at the world championships on Thursday.

Felix, the most decorated female athlete in athletics history based around her 200m and relay expertise, clocked a blistering time of 49.26 seconds, the best in the world this year.

Shaunae Miller of the Bahamas claimed silver in a personal best of 49.67sec, with Jamaica's Shericka Jackson taking bronze (49.99).

Meanwhile, Olympic champion Christian Taylor produced the second longest jump ever to win the triple jump.

The Dutch-based Taylor left it late, nailing a jump of 18.21 metres on his sixth and final attempt to add to the world championship gold he won in 2011. Only world record holder Jonathan Edwards has jumped further, 18.29 in 1995.

Cuban rival Pedro Pablo Pichardo claimed silver with a best of 17.73m as 2008 Olympic champion Nelson Evora took bronze when he went out to 17.52m with his last jump.
