Justin Gatlin and Trayvon Bromell, as expected, filled the first two 100 metres places at the US Olympic Track and Field Trials at Hayward Field in Eugene on a day when Allyson Felix backed up half of her ambition to double up in Rio 2016 by winning her 400m final.

Galen Rupp, already qualified for the Rio 2016 marathon, gave himself a second option as he lived up to his position as favourite in the 10,000 metres at the United States Olympic Track and Field trials in a race which saw the end of 41-year-old Bernard Lagat’s hopes of becoming the oldest ever American runner at the Games.

The International Association of Athletics Federations (IAAF) have agreed to an American request to alter the timetable at the Rio Olympics - which they believe will help sprinter Allyson Felix's chances of securing a golden double.

For the second time in four days, Usain Bolt held off the challenge of Justin Gatlin of the United States here to complete his world 100/200 metre double in 19.55sec, the fastest 200m time run this year, and conclude a rare night of athletics that had already been punctuated with a historic triple jump of 18.21m by Christian Taylor, the second best ever achieved.

Thomas Bach held out hope to Allyson Felix today that she might yet be able to realise her ambition of challenging for both the 200 and 400m titles at next year’s Rio Olympics.

This week’s dead heat in the Pan American Games rowing final, where Chile and Argentina shared the Men’s Coxless Pairs title in Toronto with identical times of 6min 27.77sec  caused quite a stir.
