Former distance runner Henry Rono, who set four world records within 90 days in 1978, has left two alcoholic rehabilitation centers “and has gone back to drinking,� his agent said.

Tracy Sundlun, the agent and president of the Metropolitan Athletics Congress, said that Rono voluntarily left a center in northwestern New Jersey “because it was too restricted� a few days after being admitted in late November, and was thrown out of one in eastern Pennsylvania about 3 1/2 weeks ago “for disciplinary reasons.�

Rono is living with a former running friend in Boston, Sundlun said.
