Haile Gebrselassie was a convincing winner of the Lisbon half marathon .
Ethiopia's former world record holder for the distance was untroubled when brushing off the challenges of Charles Kamathi and Semy Karanja to finish in 59 minutes, 15 seconds.
There were hopes Gebrselassie might attack Sammy Wanjiru's world record of 58mins 33secs, but the pace was never quick enough to get near it.
Gebrselassie, unbeaten in all eight half marathons in which he has competed, will now concentrate his training on preparing for the Thales FBK-Games in Hengelo where he is scheduled to race over 10,000 metres.
Japan-based Kamathi clocked a time of 1:01:15 while his fellow Kenyan finished 37 seconds behind him.
Kenya's Salina Kosgei scored a third success at the Portuguese event but was made to fight hard for her victory ahead of Pamela Chepchumba and Souad Ait Salem.
Kosgei won in 1:09:57, just two seconds in front of her compatriot and Algerian Salem, who shared the same time.
