MORZINE, France — Lance Armstrong promised a shake things up in the French Alps, but the seven-time Tour de France champion was feeling shaken after one of his worst ever days racing.

Armstrong used to be the one punishing others when the Tour hit the harsh mountains, but Armstrong suffered the frustration his vanquished rivals once felt as his Tour bid fell apart.

The 38-year-old Texan finished Sunday's eighth stage so far back in 61st place that his ambitions to win an eighth Tour evaporated in the stifling heat as he dragged his battered body up mountain passes he used to glide up.

"Obviously the Tour's finished for me," Armstrong said after Luxembourg rider Andy Schleck won the stage to move just 20 seconds behind overall race leader Cadel Evans of Australia.
