Women's 100m
Who: Candace Hill (USA), Khalifa St. Fort (Trinidad and Tobago), Ewa Swoboda (Poland)
When: Heats on Wednesday, July 20, at 12:35 p.m. local time; Semifinal on Thursday, July 21, at 6:05 p.m. local time; Final on Thursday, July 21, at 9:20 p.m. local time
Why: The top medalists from last summer's IAAF World Youth Championships are the leading contenders here in Candace Hill of the U.S. and Khalifa St. Fort of Trinidad and Tobago. Both athletes turned professional while in high school this year.
Though Hill has not recorded another sub-11 since her historic 10.98 that broke the national high school record last year, her season's best of 11.09 (+1.9) is still by far the best of the group. St. Fort enters with a new personal best of 11.16 from Trinidad and Tobago's national championships--a performance that earned her a spot on the 4x100m relay at the Olympic Games in Rio this summer.
Polish 18-year-old Swoboda is the hometown favorite. She ranks No. 3 behind Hill and St. Fort with her 11.18 PB, which set the Polish national junior record. Swoboda's most impressive accomplishment this year happened in February, when she ran 7.07 for 60m to set the world indoor U20 record.
