PORTLAND, Ore. (AP) — Galen Rupp, the Olympic silver medalist in the 10,000 meters, will step up in distance and try to qualify for the Rio Games in the marathon next month.

This will be Rupp's first full marathon. The U.S. Olympic marathon trials are Feb. 13 in Los Angeles, with the top three securing spots to Rio.

His plans for track haven't changed: Rupp, who turns 30 in May, intends to compete at the Olympic trials in July.

Rupp finished fifth in both the 5,000 and 10,000 meters at world championships last August in Beijing.

The world indoor championships in Portland in March also remain on his radar.

Rupp is coached by Alberto Salazar, who is under investigation by the U.S. Anti-Doping Agency for allegedly encouraging Rupp and other runners to skirt anti-doping rules.
