The morning session features two track events with heats of both the women's steeplechase and 400m, but the action really heats up in the afternoon with finals in the women's 10k and 100m as well as the men's steeplechase. The afternoon also features women's semifinals in the 400m hurdles and 100m and men's semifinals in the 400m.
The real intrigue of the morning is in the women's steeple, where the third heat really sticks out as a much better field than the other two. Of the seven women with PBs faster than 9:20, four of them are in the 3rd heat in Emma Coburn, Hyvin Jepkemoi, Etenesh Diro, and Sofia Assefa. With only the first three in each heat protected with an automatic qualifier, look for the third heat to go fast as all four women will want a place in the final.
The positive spin on the uneven heats is that the two other American women--Stephanie Garcia and Colleen Quigley--should have a good chance of advancing. If Coburn can survive the heat of death, the U.S. could potentially see three women in the finals.
The excitement of the evening also rests in the steeple with Evan Jager representing the best hope of a U.S. medal in the steeple since...well...maybe ever. He enters with the third-best PB in the field and second-fastest time in 2015. My non-existent money is on Jager for Gold.
