The long distance great failed in a first attempt in Berlin two months ago when his lungs seized up and he was struggling for air before pulling out.

His manager Jos Hermens says Gebrselassie’s respiratory problems have been solved and should be in top shape for the Feb. 26 marathon.

Gebrselassie won Olympic gold medals in the 10,000 meters in 1996 and 2000. He also has four world titles in the 10,000 between 1993 and 1999. At the Berlin Marathon, he lost his world record to Patrick Makau of Kenya.

Gebrselassie will run a 15-kilometer race in Nijmegen, Netherlands, over the weekend as preparation.
