One challenge down, one to go for Alexa Efraimson.

On Friday, the Camas runner qualified for Sunday's 1,500 meter finals of the IAAF World Junior Championships in Eugene.

The 17-year-old was part of a four-person breakaway pack that finished within 1.25 seconds of each other. With a time of 4:16.87, Efraimson was fourth in a qualifying heat won by Ethiopia's Gutaf Tsegay in 4:15.62.

The top four in each of two heats plus the next four fastest times advanced to Sunday's finals, which begin at 3:55 p.m.

Fellow American Elise Cranny also qualified for the finals, finishing fourth in the other heat won by Ethiopia's Dawit Seyaum in 4:14.72.

Efraimson won bronze in the 1,500 last year in Ukraine at the World Youth Championships open to athletes age 16-17. The World Juniors are open to athletes younger than 20.

"All year we've set a race plan for two events, the Nike Cross Country Nationals and the World Juniors," her coach Mike Hickey said last week. "As for the most important, I would say it's this weekend."

Skyview graduate and Washington freshman Colby Gilbert races in the 5,000 meter final tonight at 8:45 p.m.
