Prior to surfboards and salt water, Marks spent her free time in the horse stables. She rode horses competitively throughout her childhood and had a promising future as an equestrian. However, her relationship with horse riding was never like the one her brothers had with surfing. So she gave surfing a shot, and, well, you know the rest.
"It gives me the goosebumps talking about it," Marks told Red Bull. "I just really, really wanted to impress my brothers and I really wanted them to think that I was cool and accept me. They thought surfing was the coolest thing ever, so I was like, 'Well, I have to be really good at something that they think is cool.'"
