Tiki Gelana hasn't run a good marathon since her 2012 Olympic victory but has an excellent shot to resurrect her career in this less than stellar field. 2014 runner-up Birhane Dibaba (2:22:30 pb) and 2014 Paris/Commonwealth champ Flomena Cheyech Daniel of Kenya (2:22:44) should provide some competition, as will debutante Selly Chepyego (bronze at World Half Champs). American 2:28er Lauren Kleppin is basically guaranteed her first career top 10 showing at a major in this small 10-woman elite field.
