The 1999 edition of Tour de France had two bizarre moments. The first was on stage 2 when a 25-rider pile-up occurred at Passage du Gois. The Passage du Gois is a two-mile causeway which depending on the tide can be under water. A rider came down in the middle of the field during the passage, leading to the crash that cost pre-race favourites Alex Zülle, Christophe Rinero and Michael Boogerd more than five minutes to the lead group. The second bizarre incident was on stage 10, one kilometre from the summit of Alpe d'Huez. Leading Italian rider Giuseppe Guerini was confronted by a spectator holding a camera in the middle of the road. Guerini hit the spectator but recovered and went on to win the stage.
