I think that's easily her best chance. I mentioned the other day that Hassan should attempt an Ayana/Chepkoech type of devastation from the outset.
If she instead decides to settle in back per norm, then she's got major problems and the theoretical advantage is gone. You don't want Sifan Hassan trying to outmaneuver Faith Kipyegon in a tactical race.
What will happen when Hassan and Kipyegon ask full out during the final lap? IMO, that was easily the most intriguing variable entering this meet -- if Hassan chose the 1500 -- and nothing has changed my mind.
Muir and Houlihan are very good but I'll be quite surprised if a gap doesn't develop between Hassan/Kipyegon and that second tier.
During the 2017 world championships 1500 I had a wager on Kipyegon and wasn't worried in the slightest. There was no chance the flailing time trial girl was going to sustain against a freak athlete like Faith Kipyegon. There is no question it could be different this time. Hassan entered the 2017 race with the best time in the world. But in 2019 the times are more outstanding. Kipyegon appears a bit heavier than 2016 or 2017, which is obviously understandable coming off maternity leave.
But I remain surprised that so many fans are all but conceding this to Hassan. If you assign Kipyegon's identical efforts in those two races from 2016 and 2017 to Dibaba's resume and not Kipyegon's, then there is no question that maternity-leave Dibaba 2019 would be either favored or toss up against Hassan, no matter what Hassan had accomplished recently.
Very odd conventional wisdom. That's all I'm saying. Kipyegon had the baby 16 months ago. She resumed training in January 2019, according to her own words in the Prefontaine post race interview. It's not as if this has been a 3-month rush job.
