Sienna is a junior at a sports clinic who recently started training for her first 5K and is reviewing running gear as she goes. She focuses on the comfort and "real-world" fit of athletic leggings and entry-level running shoes for beginners. Her reviews are highly relatable, often discussing the struggle of finding gear that doesn't chafe or slip during a workout. Sienna is an advocate for "slow running" and finding joy in movement rather than just competition.
