Morocco's middle distance star Hicham El Guerrouj plans to retire from international athletics in 2006.
The 30-year-old clinched an historic double at the Athens Olympics where he took the 1500m and 5,000m crowns in thrilling fashion.
El Guerrouj has now set his sights on breaking Kenenisa Bekele's 5000m world record next season before a farewell season the following year.
The Morroccan also aims to add to his medals at the 2005 world championships.
El Guerouj holds the mile, 1500m and 2,000m world records and raced to his fourth consecutive world 1500m title in Paris last year.
And the Athens Games saw the talented runner end his quest for an elusive Olympic title despite dominating middle distance running for much of the last decade.
After winning the 1500m gold medal, El Guerrouj delighted the crowds as he held off 10,000m champion Bekele to win the 5,000m and complete a golden double.
