TOKYO, November 18- World-record holder Haile Gebrselassie revealed Thursday he will compete in next year's Tokyo marathon in what is set to be his first major appearance since reversing his decision to quit racing.
The 37-year-old originally announced his retirement earlier this month after pulling out of the New York marathon with a knee injury ten miles from the finish.
But the Ethiopian, who is a former Olympic and world 10,000m champion, backtracked on Monday and has now confirmed via his Twitter page he will race in Tokyo on February 27 2011.
"Did a 90 minutes run this morning, it was great," he wrote.
"No pain in my knee and relieved to know that I can continue what I love doing.
"My next race will be Tokyo marathon in February."
Gebrselassie set the current world record for the marathon in 2008 when he ran 2 hrs 03:59 mins in Berlin, breaking his own record.
