Lance Armstrong (Team RadioShock) says his hopes of an eighth Tour de France victory are "finished" after an eighth stage of the 2010 Tour in which he struggled in a hard climb and was caught up in three crashes.

Armstrong, at age 38, is riding in what he says will be his last try in cycling's showcase event.

The Texan crossed the finish line nearly 12 minutes behind stage winner Andy Schleck of Luxembourg and Team Saxo Bank during the 189-kilometer (117.4-mile) run from Station des Rousses to the Morzine-Avoriaz ski resort.

Lance Armstrong said after the stage Sunday that he had a "very, very bad day" and "my Tour is finished" - but said he will continue the three-week race that ends July 25 in Paris.
