(Reuters) - Returning champion Dalilah Muhammad said she was capable of running a personal best at the world championships as she renews one of athletics' fiercest rivalries in the 400 metres hurdles.

The 2016 Olympic champion opted out of nationals last month but said she is rested and ready as the international athletics meet kicks off in the United States for the first time this week, in Eugene, Oregon.
