Usain Bolt has moved on, but sprinters of a certain age are not yet ready to cede the spotlight just yet in the men’s 100 meters.
The world championship semifinals and final will be the marquee event of Saturday’s session in Doha, Qatar. The session also includes finals in the women’s hammer throw, men’s long jump and women’s 10,000 meters, all of which have U.S. medal contenders.
Justin Gatlin, who won the 2004 Olympic gold and 2005 world championship in the 100 meters before serving a lengthy suspension for a doping infraction, won his heat Friday to extend his effort to defend the world title he won two years ago at age 35.
