She says in the interview that her training is going better than before Chicago. I assume Chicago and London are equal courses for time.
She ran 2:21 in Chicago and is going for sub-2:20 from the gun. So obviously depending on weather, she will either run a 2:18/19 or blow up.....2:28 or something. Considering her record of not blowing up, I am going to say that she is good for the win with just as much chance for Vivian and Keitany. Could be an exciting finish.
