Lance Armstrong, the seven-time Tour de France cycling champion, won his second Half Ironman triathlon race in two weeks in Hawaii.

The 70.3-mile event in Hawaii was the fifth for the 40-year-old Armstrong, who is seeking to qualify for the Ironman World Championship after retiring from professional cycling in February 2011.

Armstrong finished second in his Ironman debut in Panama in February and was seventh in Galveston, Texas, in April. Last month, he placed third in St. Croix before crossing the finish line more than 11 minutes ahead of the runner-up in Florida on May 20.

Armstrong, who competed as a professional triathlete at age 18 before focusing on cycling, completed the 1.2-mile swim Saturday in 23 minutes, 22 seconds, placing him third. He moved into the lead after covering the 56-mile bike ride in two hours, one minute, 46 seconds and sealed the win by running 13.1 miles in 1:22:30 for a total time of 3:50:55.

Greg Bennett and Chris Lieto, both Americans, were second and third in 3:53:41 and 4:05:55 respectively.

Armstrong, who won the Tour de France each year from 1999 to 2005, is scheduled to race a 140.6-mile full Ironman event June 24 in Nice, France, in his quest to earn enough points to qualify for the world championship in Hawaii on Oct. 13.
