Glancing up, I notice a lady step off to the side of the trail. Alone, she was coming downhill as I was heading up and I found her gesture very premature, but much appreciated. Most trail users are considerate, but her stepping aside while so far away was unusual.
I maintained my focus on the trail as it was cluttered with loose rock and my proprioception (fancy college word of the day) was key in not getting hurt. While chugging up the hill, I noticed the lady had remained motionless at the side of the trail. Since most wait for the final yards to step aside, including me, her behavior was odd. Music was setting a good rhythm during the ascent and while nearing her, sheer terror distorted her face while staring right at, or behind me.
