Haile Gebrselassie, one of the most accomplished distance runners in history, has been going through a bit of a career slump lately, but he's definitely not finished.

The Ethiopian returns to perhaps his best race, the marathon, this weekend at the 66th Fukuoka Marathon in Japan.

"I don't know exactly how fast I can run [Sunday] but I can run a good time," Gebrselassie told the Herald Scotland. "I don't know, between 2:05 and 2:06, it depends. I mean, their course is so nice and it depends on the weather.

"For the moment I am in good shape and what is important is my health is very good. The only problem is that I have office work now. I cannot take rest after morning training sessions anymore. My training is going well, though, and according to the program."

Gebrselassie (who won in Fukuoka in 2006) set a marathon world record with a time of 2:03:59 four years ago in Berlin, a mark eclipsed by Patrick Makau (2:03:38) in Berlin last year.
