Thanks to everyone who responded to the poll. Unsurprisingly almost half hadn’t heard of #reynauds, a condition as common as hay fever. It causes vasoconstriction, notably in the hands and feet, and #runners that get it might have it before and after a #run, not usually during (unless it’s really cold and a slow run). It can be a symptom if more serious auto-immune conditions. I’ll share a post with followers on how it affects me and what I’m doing to raise awareness about it. 🙂
