I was 13:00 min into what I planned for a 30 minute run, still heading out when I stepped funny with my left foot. It was a slight roll, and I collapsed downwards on the leg to lessen the impact. However I only stumbled and didn't stop running.
It felt a little funny, but it was warm, and I kept going, although a little slower. I was worried it was going to be hurting, but it felt OK on the way back, and after a 15 minute cool down, it still feels fine. I think I'll still add some ice.
