Mare Dibaba enters the 2014 Bank of America Marathon with the third-best time in the field, a 2:19:52 she clocked at the 2012 Dubai race.
The Ethiopian already has a win under her belt this year, winning the Xiamen Marathon in a course record 2:21:36.
Other career highlights include a second place finish in the 2011 Toronto Marathon, a third place finish in the 2011 Los Angeles Marathon and a third place finish in the 2010 Rome Marathon.
Dibaba is one of several participants with the talent to break 2:20 on Oct. 12, but even that won't guarantee a win among this solid field of athletes.
