I don't like Obiri but credit for that effort. She is a strange case because she lumbers along and sometimes you can sense she absolutely doesn't have it and will fade at the end, while in other races she keeps going and wins impressively.
There is almost never a middle ground with her in which she runs well but finishes second.
However, that would have happened in this race had Hassan entered. Obiri is no match for Hassan right now and she benefits more than anybody from Hassan's win in the 1500 today. If Hassan had lost that race she very likely would have switched to a 10,000-5000 double for Tokyo. Now she'll probably do the same program again, especially since the 1500 is more of a glamour race and she would receive more credit.
At least Klosterhalfen entered the 5000 and made Obiri earn it. It seemed very clear that Klosterhalfen was determined to pick the race that Hassan avoided.
Klosterhalfen has very poor strategic instincts at this stage of her career. It is not unlike Hassan several years ago. Klosterhalfen can make the big early sustained moves against lesser fields but somehow doesn't recognize that the same tactic won't work against premier foes. At current level she would be much better suited to draft then show her cards late.
But she doesn't have the springy athletic ability to improve as Hassan did. I think Klosterhalfen's best bet is to work on early sustained speed, like Ayana did. Basically I think that is a great tactic for just about any serious contender. These women's distance races are still slower per lap than they should be. But the number of legitimate threats during the final lap of that 5000 today demonstrated where we are headed. Very soon you won't be able to dawdle along at the old accepted standards.
