TOKYO — It happens so fast. After years of preparation, Lakeville's Regan Smith and her rivals walk to the pool, discard their robes and flip-flops, and dump them into a laundry basket set there by workers as a low-tech, moveable locker.
The swimmers quickly stretch or leap, or slap their thighs to awaken their muscles, then approach the edge of the pool.
On Monday morning in Tokyo, Smith was racing in the 100-meter backstroke semifinals, so she leaped into the pool, took her starting position and then arched back into the water.
She won the first heat in an Olympic record 57.86 seconds. For the second straight day she had set the record. This time, she held onto it, taking the record into Tuesday's final.
"It was great," Smith said. "I'm really pleased with it. I was just trying to clean some things up from last night and get ready for tomorrow. So I'll definitely take that. I'm really happy with it."
The Olympic and perhaps world record is likely to be broken in the final.
"Ultimately, it doesn't matter," Smith said. "Tomorrow is what I'm really shooting for. But, yeah, I feel great and hopefully I can just keep the ball rolling and keep the energy flowing into tomorrow."
It happens so fast. On Sunday night, Canadian Kylie Masse, in the fourth heat of the prelims, had set an Olympic record in the 100-meter backstroke at the Tokyo Aquatic Center.
