After revealing her RED-S diagnosis earlier this month, Chloé Dygert (Canyon-SRAM) has explained how unusual symptoms and the lack of a weight problem made the diagnosis both difficult to identify and surprising to her and her coach.

RED-S, or relative energy deficiency in sport, is often associated with under-fueling and low body weight, and in women, the loss of a regular period.
