I fell over while running last week and I wondered if anyone else had had a similar experience. I feel previously about 6 months ago and it was exactly the same. I did not trip over anything. I know I did not black out or anything dramatic like that. It just felt as if the ground was higher up under my left foot than I expected and over I went onto my face! Only a few bruises and scrapes but I don't want to be put off by feeling it will happen again.
