Maebashi, Japan- The Associated Press Haile Gebrselassie will try and prove that the name of the current movie documentary about him called "Endurance" is a fitting title. The small, slender Ethiopian will attempt an unprecedented 1,500 meter-3,000 meter double at the World Indoor Championships, beginning today. "It will not be easy to run both," he said Thursday. "But I think I can run three days without a problem. If there is a problem, it will come in the 1,500."
