LEADVILLE, Colo. (AP) _ Lance Armstrong finished second in the Leadville Trail 100 mountain bike race today, pushing six-time champion Dave Wiens to a record time.

It was Armstrong's first competitive bicycle race since winning his seventh straight Tour de France in 2005. Wiens took the lead from Armstrong with 10 miles to go in the 100-mile race and finished 1 minute, 56 seconds ahead.

Wiens crossed the finish on a flat back tire in a time of 6 hours, 45 minutes, 47 seconds, shaving 13 minutes off his old record. He set the record last year while holding off Floyd Landis.
