In 2000 Otxoa won a heavy mountain stage in the Tour de France on top of the Hautacam. In February 2001 a car hit him and his twin brother Ricardo during training. Ricardo died. Javier survived but was in a coma for a month and became seriously disabled. He continued cycling, however. In the 2004 Summer Paralympics he won a gold in the road race/time trial event and a silver in the individual pursuit.
