Marley Blonsky felt like an imposter before she rode her first century. As the founder of the size-inclusive biking initiative All Bodies on Bikes, cycling was her job. She had been riding for years — why hadn’t she pedaled into the triple digits yet?

To offer some context, UNBOUND is a particularly stiff entry point for a first-time 100-mile rider. Here, you’ll watch Blonsky battle conditions and cutoff times on her way to the century mark.

“I have chills thinking about what it’s going to feel like to finish, and accomplish this goal — with everybody else who also has these goals,” Blonsky said near the start of the short film.
