Felix advances in first race in 13 months

New York - The 33-year-old multiple Olympic and world champion is on the comeback trail after giving birth to daughter Camryn

A humble Allyson Felix returned to racing for the first time in 13 months on Thursday and made the semifinals of the 400 metres on a time qualifier at the US national championships.
The 33-year-old multiple Olympic and world champion is on the comeback trail after giving birth to daughter Camryn in November through an emergency caesarean section, 32 weeks into her pregnancy
Heats dominated much of the opening day of the four-day trials that will determine the American team for September's world championships in Doha.
World champion Justin Gatlin finished second to training partner Isiah Young in their 100 metres heat, while 2017 world silver medallist Christian Coleman won his.  
Gatlin, 37, was clearly enjoying the moment and he and Young pointed to each other in celebration as they approached the line.
"We just wanted to go out there and just run through 70 or 80 metres, then look over at each other and basically say good job," Gatlin said.
Young ran 10.14 seconds, the fastest time of the day, with Gatlin crossing the line in 10.16, second fastest.
