Her form in Boston was still suited to a track race. It's poor form for 26.2 miles. If she doesn't fix that, her legs will not be fresh for the last 10K.
I think she doesn't go under 2:20, but she will set a PR.
Also, the reason these races are not well followed is not because the focus is on time, or whatever. It's because the prize money is barely worth the turn of a head. $150,000? I don't even know if it's that. The races won't even advertise it. Nor will they advertise how much they pay the runners just to show up. It's pathetic.
Make the top prize 1 million dollars. Make second place 250,000. Third, maybe 100 or something. Ignore the appearance fees and make them race because if they don't they get nothing. That's what makes the race exciting and that's what could help kill off the fixed or thrown races (Mutai, Farah wins).
And ... that's what will get people to pay attention. $150,000 is chump change. Yes I know, it's a lot of money to people fresh out of college, etc... But when you hear about athletes signing million dollar deals and endorsements worth millions, and then you see African runners winning races while the organizers applaud a 100,000 figure payday, I mean it looks pathetic in comparison.
