I think the extra racing she did in the first two rounds finally caught up with her. You can't run three rounds out in lanes 2 and 3 and expect to have much left in the final. She's raced that way in the past at World Juniors and Youth so we'll have to wait & see if she makes adjustments.

Simpson was pretty darn tough. Not quite the magic of 2011, but I think this really cements her at this level for this event. I remember some thought 2011 was fluky.

Surprised. I thought Cain would have raced a bit smarter and perhaps started moving up with about 500 to go before everyone started sprinting.
