Sore knee stops Lance Armstongs triathlon training

Lance Armstrong, the seven-time Tour de France winner, will not compete in a New Zealand triathlon next month because of a sore left knee. Armstrong had planned to compete in a sprint triathlon, but in a phone interview he said the knee condition had forced him to stop his training runs. The injury has not interfered with his cycling. Armstrong still plans to compete in the Tour Down Under cycling race in Australia that begins Jan. 16.
