Nicola Spirig, Switzerland. Age at the Olympics: 30
Although Spirig is a two-time European champion, multiple medalist at World Triathlon Series events, and the overall silver medalist for the 2010 series, she was somewhat off the radar last year due to stress fractures that prevented her from racing up to her typical form. These injuries might be a blessing in disguise, however, as they gave her an opportunity to work on her swim—her one major weakness. If her swim is good enough for her to make the first pack in London, her phenomenal biking ability combined with her fantastic run speed make her a contender for a medal—and don’t be surprised if she wins gold. Even if she misses the first pack, she’s known for pulling the pack she’s riding with up to the front, which means there are multiple scenarios through which Spirig can come out a medalist.
