Hi, I’m new to this forum but am interested to see if anybody has experienced the same sensation as I did this morning. I have been running 2/3 times a week for about six months, just keeping distance at 5k to encourage my heart to keep beating (it’s 63 yo). Anyhow, today as I slowed down at the end of a 5k, my legs would not stop running. I had several attempts to stop as usual but to no effect and eventually staggered into a tree (tree was fine by the way, me, less so). This took about 5-10 seconds t9 elapse and has left me totally puzzled, is it some kind of muscle memory thing and if so, why did it occur this time only?
