Rafael Nadal and Roger Federer Tennis Records

Rafael Nadal holds the record for longest winning streak on a single surface (clay) with 81 consecutive victories between 2005-2007. This surpassed the previous record and remains unbroken. The 30 and 31 options are too low for such a record.

Rafael Nadal holds numerous records in tennis, particularly on clay courts where he dominates with 14 French Open titles and an 81-match winning streak. While Federer also holds records (most weeks at world No. 1, 20 Grand Slam titles shared with Nadal and Djokovic), this question refers to Nadal's clay court achievements.

Rafael Nadal's unparalleled record of 14 French Open titles and 63 clay-court titles earned him the nickname 'The King of Clay.' His dominance on this surface is statistically the greatest in tennis history by any margin.

Rafael Nadal won the Olympic gold medal in men's doubles at the 2008 Beijing Olympics, partnering with Marc López. This was his first and only Olympic gold medal. The statement is factually correct.

Nike has been Rafael Nadal's clothing and shoe sponsor throughout his professional tennis career. His signature shoe line is the Nike Air Max Courtballistec. The other brands (Puma, Reebok, Adidas) sponsor other tennis players but not Nadal.

Roger Federer holds the record for most consecutive weeks at World No. 1 in the ATP rankings, with 237 consecutive weeks from 2004 to 2008. Nadal has spent many weeks at No. 1 but not consecutively for as long. 'Both' and 'None' are incorrect.

Roger Federer holds the record for most consecutive wins on both grass courts (65 matches from 2003-2008) and hard courts (56 matches from 2005-2006). His dominance on grass included five consecutive Wimbledon titles from 2003-2007, while his hard-court streak included wins at the US Open, Australian Open, and various ATP Masters events. Nadal's consecutive win records are primarily on clay courts.
