22: Abbey Brau
Abbey had been a competitive swimmer in high school, but after she was diagnosed with type 1 at 22 years old, it took a while to relearn how to swim, not to mention live life normally, again. But when the non-profit Beyond Type 1 was putting together a team of 20 people with type 1 diabetes to bike from New York to San Francisco in the summer of 2017, Abbey signed up. When that was over, she looked for something even harder.
