On this busy day, Tianna Bartoletta didn't know whether to run or jump.

Bartoletta shuffled back and forth between the long jump and the 100 meters at the U.S. Track and Field Trials on Saturday. Everything went according to plan, too, as Bartoletta finished second in the long jump to earn a place on the Olympic team and also advanced to the semifinals in the 100.

An exhausting but exhilarating day.

"I didn't come into today trying to win the long jump because I knew it would be a difficult task having to run the 100 between rounds," Bartoletta said.

Bartoletta made one leap in the long jump _ her best one of the day _ before switching over the 100. She returned to the sand pit for one more leap before passing on her final two attempts. She finished Brittney Reese, with Janay DeLoach taking third.

"It's difficult," said Bartoletta, the 2005 and '15 world champion in the long jump. "The runway requires a certain rhythm, whereas the 100 requires a certain recklessness. If those wires get crossed, your approach can be off or your 100 can be slow."
