The evening session is coming up.
If you missed the morning session, you diidn't miss much. You can read our recap of the women's 800 prelims from that session here:
Also this morning, the 60mh heats were held and Venezueal's Yulimar Rojas won the triple jump (47 feet, 3 1/2). Heats were also run in the 4 x 400 to eliminate 1 team.
Tonight's evening session shoudl be great, however.
Tonight's session will feature finals in the following events on the women's side - 60m, 400m, 1500m, and shot put. On the men's side, finals will be held in the 60mh, 400, 800, triple jump and high jump. Also the men's heptathlon will conclude.
In heptathlon, Ashton Eaton is on track for yet another gold medal as he has 238 point lead on the Ukraine's Oleksiy Kasyanov (who is way worse at the 1k than Eaton - 2:39.44 pb) but there is no chance Eaton gets a WR. Eaton has done a little worse this year in every single event (7 to 37 points per event) than what he put up in 2012 when he set the 6645 WR as shown here:
The 1k should be exciting however as American Curits Beach - who has a 2:23 1k pb - is in 6th place. Beach is 186 points out of second. To get the silver, he'd have to beat Kasyanova by 16.55 seconds which seems unlikely.
The more interesting question is, " can Beach get bronze?" To catch Germany's, Mathias Brugger, whom Beach trails by 67 points, Beach needs to beat him by 5.8 seconds (as well as beat the others ahed of him in the standings). Brugger has a 2:38.05 pb.
