Moscow - Sprint star Allyson Felix said Wednesday she was enjoying being elder stateswoman of the US squad as she prepares to concentrate on her favourite 200m event at the World Athletics Championships in Moscow.
Felix, 27, has performed at 100m, 200m and 400m during an illustrious career but the majority of her medal-laden success has come in the half-lap discipline, which is her sole focus in Moscow.
"I am excited to be back at the world championships and focus on the 200 which I have not done in quite some time, get back to where I started from and enjoy the World Championships," the London Olympic 200m champion told reporters in Moscow.
"I also hope to be on both relays here." she added.
Felix is aiming to reclaim the world 200m title she lost in Daegu two years ago when finishing third, having gone into that championship as the triple world champion at her best event.
Felix, for so long the young standard bearer of US athletics, also said that it felt strange to be one of the oldest athletes in the US squad and to serve as a mentor to the younger ones.
"I am old now!" she said laughing. "It is very weird, time is going by... and it's a lot of fun to see the younger athletes come up.
"It is great to be able to give them advice, make sure they stay focussed and enjoy the journey and all that. They have blank pages in front of them, it is the beginning of their careers.
"It is definitely a different experience to be one of the older people on the team."
