POITIERS, FRANCE, JUNE 29 -- Can Greg LeMond do it again?

Last year, he astounded everyone by coming from behind on the last day to win the Tour de France for the second time.

Outside demands took their toll on LeMond over the winter, and a virus slowed his attempts to get back into shape even more.

But as the 1990 race begins Saturday in a high-tech theme park called Futuroscope, people still keep a wary eye on the only American to win the Tour de France.

"I feel pretty good. Things are coming around just on time," LeMond said this week. "I'm not sure I'm going to be turned around 100 percent for the Tour, but I will be there."

But even a less-than-100 percent LeMond is dangerous. He has geared his whole year on to winning this race for the third time.

His toughest competition could come from three other former champions -- Irishman Stephen Roche, Pedro Delgado of Spain and Laurent Fignon, the French star narrowly edged by LeMond last year.

Fignon, the 1983 and 1984 winner, started the season well. But he fell heavily in the Tour of Italy and lost valuable training time.

Delgado won in 1988 but had trouble last year when he wound up nearly three minutes late at the start of the prologue.

Roche won in 1987 but has had knee problems since.

LeMond, after winning in 1986, missed the next two years while recovering from an accidental shooting and various illnesses and ailments. He went into the Tour last year as a question mark and came out a winner.

The demands placed on LeMond as a Tour de France winner were so great that he cut himself off from everything except cycling over the past two months, and he has made progress, both physically and mentally.

LeMond, though, now feels he is in good shape. "After the Tour of Italy we went motor pacing behind a motorcycle. I was going behind the motorcycle faster than I have ever gone -- 80 kilometers an hour {50 mph}. I know from other years when I am in good shape I do 60-65 kilometers an hour. This time I was always around 70 and for the sprint I did 80."

LeMond doesn't know who to focus on this year.

"It's hard to say who is riding well," he said. "Last year I knew who my main competitor was -- Fignon. He was riding so well, I knew he was dangerous. Now, I don't know who is dangerous because nobody has really showed themselves."
