Some York County athletes are competing at the 2012 U.S. Olympic Swimming Team Trials in Omaha, Neb., this week.

The event started Monday, June 25, and will continue through Monday, July 2.

York Suburban High School graduate Julia Kucherich, a junior-to-be on the University of Arkansas swimming team, has garnered the top performance among local swimmers thus far, placing 30th in the women's 400 individual medley with a personal-best time of 4 minutes, 51.16 seconds.

The York native entered the competition with the 76th-best seeded time and improved on that mark by more than a second in the prelims of the race. She finished just eight seconds off of qualifying for the event finals.

"Julia went after it and had a great swim," Arkansas coach Todd Mann said on the Arkansas website.

The IM race is the first of two competitions for Kucherich. She now looks toward Saturday's 200 backstroke.

Also in the women's, 400 IM, Spring Grove High School graduate Hali Flickinger finished 60th in 4:55.66. She came into the event seeded 16th in a time of 4:44.15.

Flickinger, who swims for the York YMCA, also finished 43rd in the 400 freestyle in 4:17.74. The Georgia recruit came into the event seeded 69th in 4:17.42.

Flickinger is expected to also compete in the 200 IM on Wednesday, the 200 butterfly on Thursday and the 200 backstroke on Saturday. Kacey Oberlander, who is expected to enter Dallastown High School this fall, is also scheduled to swim in the 200 backstroke. Oberlander is just 14.

Another York County swimmer, Caleb Tuten, finished 92nd in the men's 400 IM in a time of 4:34.97. Ryan Lochte won that event in 4:07.06, followed by Michael Phelps in 4:07.89.

Tuten is from Glen Rock and swims for Princeton University. He came into the event seeded No. 104 with a time of 4:30.06.

Another local swimmer, Dallastown High School graduate Brandon Flynn, finished just behind Tuten in the 400 IM in 98th place in a time of 4:36.96. Flynn, who also swims for the York YMCA, came in seeded 85th in 4:29.49.
