REVEL, FRANCE, JULY 16 -- Greg LeMond is after Claudio Chiappucci's yellow jersey. So are Eric Breukink and Pedro Delgado. But Chiappucci, the current Tour de France leader, is not ready to give up the honor.

"For the past three days I'm asked when I am going to lose the yellow jersey," Chiappucci said. "I still have it on my back. I still have chances and I have nothing to lose. It's up to the others to attack and take it from me."

That attack will take place Tuesday on the slopes of the Pyrenees leading up to Luz Ardiden. Today's 15th stage resolved little as the leaders again spent a day back in the pack, unconcerned about the activity up front.

LeMond, Breukink and Delgado conserved their energy as Charly Mottet of France won the 105.5-mile leg from Millau to Revel in 4 hours 13 minutes 56 seconds.

Chiappucci leads by 1:52 over Breukink, 2:24 over LeMond and 4:29 over Delgado. In today's leg, they finished almost five minutes behind Mottet, with only a slight change. Chiappucci added three seconds to his lead by sprinting away from the pack to finish 22nd. LeMond was 36th, Breukink 39th and Delgado 51st.

Temperatures cooled slightly to about 80 degress with a gentle breeze as the Tour headed southward for the next leg. For the first 100 miles of the 133.5-mile 16th stage, the course will be relatively flat. Then the real race begins.

Over the final miles, three of the most difficult peaks are scaled. One is rated first category and the other two are rated "out of category" on a ranking measuring steepness, length and difficulty.

LeMond, the two-time champion, feels that the key to the race will be the final two mountain stages, especially the route to Luz Ardiden. But LeMond was close-mouthed about his strategy.

"If I told it, everybody would know," LeMond said. "Besides, I don't really know what I am going to do yet. Whatever it is, I hope it will make the difference."
