Floyd Landis (born October 14, 1975) is an American (United States) cyclist (road bicycle racer) from Farmersville, Pennsylvania who was stripped of his title (for a doping offense) after initially being awarded victory in the 2006 Tour de France. As of March 2010, he rides for the Bahati Foundation Pro Cycling Team. Prior to signing with Bahati, he rode for OUCH Pro Cycling Team (UnitedHealthcare-Maxxis), throughout 2009. He is an all-around rider, with special skills in climbing and time-trialing, and is also known to be a very fast descender. Landis turned professional in 1999 with the Mercury Cycling Team. He joined the US Postal Service (US Postal Service presented by Berry Floor) team in 2002, and moved to the Phonak Hearing Systems (Phonak (cycling team)) team in 2005. In January 2010, a French judge issued a national arrest warrant for Landis on computer hacking charges related to the 2006 doping allegations.

In 2006, Landis won the first edition of the Tour of California (2006 Tour of California), before going on to finish first in the 2006 Tour de France. He was stripped of his Tour de France victory and fired from the Phonak team after a drug-control test demonstrated the presence of a skewed testosterone/epitestosterone ratio (Floyd Landis doping case) during stage 17.

Until 2010, Landis maintained his innocence, and mounted a vigorous defense. Although Landiss legal team documented inconsistencies in the handling and evaluation of his urine samples, the disqualification was upheld.

He was suspended from professional competition through January 30, 2009, following an arbitration panels 2-to-1 ruling on September 20, 2007. Landis appealed the result of the arbitration hearing to the Court of Arbitration for Sport, which subsequently upheld the panels ruling.

During the 2008 season, Landis worked as an advisor for Rock Racing. After completion of the suspension, Landis joined OUCH Pro Cycling Team (UnitedHealthcare-Maxxis). His first race following his suspension was the 2009 Tour of California, in which he finished 23rd out of a field of 84 riders. He parted ways with the OUCH team at the end of 2009. He then raced the Tour of Southland in New Zealand in November 2009 with local team CyclingNZshop.com-Bio Sport.

On May 20, 2010, after almost four years of contesting the allegations against him, Landis admitted to continual doping and alleged that Lance Armstrong and many other top riders who rode on his team doped as well.
