Joseph M. Wiley,
I hope that you are serious about your description, because I think you are right. While complete blindness would end her career as an elite runner, it is a given that she has heightened senses due to her impaired vision, and it goes much beyond the physical.
Keep the body strong with the ingestion of soy. Lots of green leafy vegetables and fruit clean the colon like an agur and prevent the formation of cancer-causing polyups. Stir fry your way to better health (tofu is your friend). Adopt twice-daily meditation and spend at least an hour each day navigating with your mind's eye.
