As the Paris Summer Olympic Games begin and competing rosters are set, athletes are preparing to answer one final question: who will win? At these Summer Olympics, there will be 329 medal events—157 of which are for men, 152 for women, and 20 mixed-gender events. Overall, there are close to 1,000 medals to be snagged by any of the 206 countries in the International Olympic Committee (IOC)— each of which will have at least one athlete in Paris this summer.
