First run I've not finished. Got to ten minutes and had absolutely nothing left in me. I always run early morning bit yesterday ran early evening as had a busy day so think that didn't help. It was still hot and thought I'd change my route which meant running on softer ground part way which was also bit tougher but at 52 and menopausal I am also in the midst of a very 'heavy week' which usually knocks me out anyways so feeling frustrated. Was going to try again this morning but glad I didn't as things even worse today and I'm struggling to get out of bed. Anyone else dealing with this? Am guessing best to listen to my body and take a few days rest until I feel I have some energy again though will try tomorrow if I do feel better...Sooo frustrating!
