Ethiopian distance-running great Haile Gebrselassie will attempt to break the world one-hour record this year.
The double Olympic 10,000m champion will be looking to beat the 21.101km mark set in 1991 by Mexico's Arturo Barrios in La Fleche, France.
Gebrselassie ran at Holland's Hengelo track last month to assess his chances.
"I want to attack the world one-hour record soon," the 34-year-old told Reuters. "My speed is still there and everything looks okay."
Gebrselassie retired from the track to concentrate on the marathon after finishing fifth in the 2004 Athens Olympics 10,000m final.
He was forced to pull out of an attempt on the world one-hour mark in Hengelo in 2002 with cramp in his right leg.
Gebrselassie was scheduled to have another crack at the record at the same venue last year but withdrew beforehand.
His Dutch manager Jos Hermens set a world record for the rarely-run event in 1976.
In an illustrious career, Gebrselassie has set 17 world records and won four world 10,000m world titles in a row.
He will not run in the World Championships this year in Japan but plans to compete in the marathon at next year's Beijing Olympics and continue until the 2012 London Games.
