American Allyson Felix hopes a lighter load will yield better results at the World Championship in Moscow, Russia.
Felix was unseated as world 200metre champion by jamaica's Veronica Campbell-Brown in Daegu, South Korea.
Unlike two years ago, Felix will not have the
400 metres, or the 100 as at the Olympic Games last year.
She expects this will work in her benefit.
“Last year was a big year, everything came together. I’ve taken it slowly this year an remaining healthy. I’m taking it slowly, still having, still enjoying it, to see if I can put together a good performance.
