Rosa Klöser, winner of Unbound

The Adventure Stache

In just two short years, Rosa Klöser went from never having ridden a gravel bike to winning the biggest gravel race in the world. Between her first gravel ride in 2022 and standing on the top step of the Unbound podium in 2024, she also managed to spend some time as a visiting researcher at MIT as part of her PhD work on the green transition of the maritime industry. Rosa catches up with Payson this week to talk about how she discovered her talent for gravel by accident during a trip to Girona, how she balanced her PhD studies with late night training rides, and why her area of research has implications for all of us. She also takes us inside her rocky Unbound experience and explains why she was, uncharacteristically according to her, cool as a cucumber by the time that nine-person sprint rolled around.
