Emma Snowsill, Australia. Age at the Olympics: 31
When Emma Snowsill is on, she’s on, and no one can beat her. The question is whether Snowsill will be on at the London Olympics. Given all that she’s accomplished in the sport—Olympic gold medalist, three-time world champion, two-time Hy-Vee winner—it would be understandable if Snowsill just couldn’t quite get up for London. On the other hand, considering that Snowsill is possibly the sport’s best big-day racer, if Australia selects her for the team, chances are high that she’ll be ready to roll come August. So let’s just put it this way: If she wins gold, don’t be surprised.
