The U.S. Olympic Trials will be at the half way point after Day 4 concludes.

Today, swimmers will battle in three Finals.

The participants in the Women's 200M Freestyle will be decided today and all eyes will be on Lane 5, which will be occupied by Allison Schmitt.

The 22-year old continues to impress in the trials and recorded a 1:55:59 to help her qualify for the Finals.

Her time was two seconds ahead of the rest of the female swimmers that raced in the 200M Semis on Wednesday night.

Michael Phelps will highlight the Men's 200M Butterfly.

He does not have to worry about Ryan Lochte taking the spot from him. Phelps should be able to outshine the other swimmers on the race. Do not be fooled by the 3rd best, 1.56.42 that he posted Wednesday night in the Semis. This is Phelps' event.

The last Finals taking place Thursday night is the Women's 200M Individual Medley.

Wednesday night, Caitlin Leverenz and Elizabeth Pelton finished in first and second to qualify for the Finals. 

The other three races of the night will be Semis.

The Women's 200M Butterfly will be slimmed down to eight. The Men's 100M Freestyle and 200M Backstroke Semis will also take place. 

You can tune in to NBC at 8PM EDT to catch all action from Omaha. It is guaranteed that for an hour you will enjoy pressure packed raced and London 2012 is still about a month away.
