Britton Wilson doubles like nobody else in track and field

Sprinter Britton Wilson regularly updates a vision board in her apartment living room. As of last week, there were two numbers on it among a collage of pictures: 48 and 52.

The 48 is for the 400m. Wilson’s short-term goal is to become the third U.S. woman to break 49 seconds in the one-lap event after Olympic gold medalists Sanya Richards-Ross and Valerie Brisco-Hooks.

The 52 is for the 400m hurdles. She wants to become the 10th U.S. woman to break 53 seconds in that event.

They are not far-fetched ambitions. Wilson, a University of Arkansas junior, has already run 49.13 in the flat 400m and 53.08 in the 400m hurdles. She is the only woman to rank among the 25 fastest in history in both events. She is the fourth-fastest American all-time in the flat 400m, passing Allyson Felix last month.

At this week’s NCAA Outdoor Track and Field Championships in Austin, Texas, Wilson will bid to become the first person to win Division I titles in the same year in both the 400m and the 400m hurdles.

On Thursday night, she will race the 400m semifinals just after 9 p.m. local time. A half-hour later, she will race the 400m hurdles semifinals. If she advances, she will race the two finals Saturday with a scheduled 24 minutes in between.

In most cases, a runner would only race twice in that short of a turnaround for the 100m or 200m. Wilson is not only attempting a rarity, but she is also the clear top seed in both events.

Last year, Wilson won both at the SEC Championships with about an hour in between the finals, then entered only the hurdles at the NCAA Championships. She won all of those races. This year, Wilson again won both at SECs. Afterward, she met with coach Chris Johnson, who asked what she wanted to do at NCAAs. Wilson chose
