Allyson Felix: World Athletics Championships record-breaker on life-changing year bbc.com

Allyson Felix is a record-breaking sprinter, a six-time Olympic champion, activist and mother. It's not only titles that define her.

Having a baby has also given birth to the activist hidden inside her. Felix is no longer a willing participant in the "culture of silence" around maternity rights in elite athletics. She has found her voice.
Felix the mother is running late. We meet on the 42nd floor of her hotel overlooking the Persian Gulf.

With the World Athletics Championships in town, these plush surroundings are perfect for a six-time Olympic sprint champion, but not for 10-month old daughter Camryn it seems. Her body clock has yet to adjust to the Middle East and as a result Felix, 33, has been up all night.
