Mastro, 21, is part of a growing number of athletes who are using their popular social accounts to connect directly to newly-converted fans, answering questions about their training routines, accommodation and Olympic merchandise at the Beijing Games.
Eileen Gu, a star freestyle skier, has been posting regular Instagram updates, including a video of her walking a “catwalk” in her room after trying on all of Team China’s different uniforms. After Mastro failed to advance to the halfpipe final, she waited some time before updating her more than 540,000 followers.
