At age 16, Armstrong began competing as a triathlete and was a national sprint-course triathlon champion in 1989 and 1990. In 1992, Armstrong began his career as a professional cyclist with the Motorola team. He had notable success between 1993 and 1996 with the World Championship in 1993, the Clásica de San Sebastián in 1995, Tour DuPont in 1995 and 1996, and a handful of stage victories in Europe, including stage 8 of the 1993 Tour de France and stage 18 of the 1995 Tour de France. In 1996, he was diagnosed with a potentially fatal metastatic testicular cancer. After his recovery, he founded the Lance Armstrong Foundation (now the Livestrong Foundation) to assist other cancer survivors.
