(NEWSER) – Tracy Barnes won a spot on the US Olympic biathlon team Sunday, but she's not taking it. She gave up her place so her twin sister, Lanny, could go instead. Lanny had been too sick to compete in all the selection races, but Tracy believes her sister had a better year and would have made the team if not for the awful timing of her illness. "She had a stellar year," Tracy tells USA Today. "She just had a bit of bad luck getting sick. I would have loved the opportunity to represent my country but it means more to me to give Lanny that chance."
