Harriet “Haz” Burbidge-Smith, 25, can’t remember a time when she did not ride a bike. She started racing BMX around the age of 4 in her hometown of Canberra, Australia, and hasn’t stopped since. “I was so pumped to be there every time,” she recalls. “I’ve always known that the bike is my happy place.” That kind of passion for riding helped propel Burbidge-Smith to eight Australian national championship titles in BMX and fueled Olympic dreams.
