No positive doping results among 189 riders

CHALLANS, France -- All 189 riders set to compete in this
year's Tour de France were cleared to race after undergoing blood
tests Thursday.

The 21 teams were tested over a two-hour period and no positive
results were found, race medical inspector Marc Vandevyvere said in
a statement. Last year, Gorka Gonzalez of the Euskaltel Euskadi
team was the only rider banned from competing after failing the
pre-race blood test.

The Tour starts Saturday with a 11.8-mile time trial from
Fromentine to Noirmoutier-en-l'Ile, and ends July 24.

Lance Armstrong, going for a seventh straight Tour title, will
retire from cycling at the end of the Tour.
