Can't run for a record AND try to win the race against a world class field. Those goals usually conflict with each other. In Simpson's case the record went out the window in the second K. To her credit, she tried to get the record back in play by taking the lead with two laps to go. Simpson usually never leads until the last lap. But taking the lead early probably cost her a higher place, maybe even the win. Simpson's best chance at the record would be (like Drake) a paced race with no competition. Problem is, there's nobody who can pace her for 6 1/2 laps at 8:25 pace. Five laps would probably be the max for a pacer which would mean Simpson would have to run the last third of the race by herself. Very tough.
