Female Athlete Glycogen Threshold Cycle
Female athlete glycogen threshold cycle adjusts carb timing by menstrual phase—the same ride may need earlier fuel in luteal weeks when late-session fade appears without more intensity.
Female athlete glycogen threshold cycle tracks how menstrual phase shifts carb needs for the same session—follicular athletes may finish long rides on moderate fuel while luteal weeks demand earlier intra-workout carbs to avoid late-session fade. Estrogen and progesterone influence substrate use; under-fueling in any phase raises RED-S risk.
Pre-session carbs scale with duration and intensity, not willpower. Post-session replenishment matters more when two-a-days stack.
Common questions
-
Do women need more carbs at certain cycle phases?
Needs follow training load first, but many athletes benefit from earlier carbs in luteal hard sessions. Log bonk patterns beside phase tags and adjust timing before cutting volume.
