I am 50 years old and in perimenopause. Hot flashes are very bothersome. Have been to naturopath and family doc. Taking estrodial and promethium, till the hot flashes calm down, then will switch over to naturopathic meds. Been very healthy all my life (very fortunately) and have been a runner for 21 years. I feel a definite change in my body and "running time" (slower) when on estodial and prometrium. Also have had high blood pressure readings (e.g., 160/95) since being on HRTs. Is the impact on running common among women taking HRT for hotflashes? Thank you in advance for your time, Mag
