Because one of us is blind (Hi, I’m Dave.) I have Leber congenital amaurosis (LCA). It’s an inherited retinal disease characterized by severe vision impairment or blindness at birth. I can see if a light is on but not much beyond that.
The second athlete is the guide. (That’s me, Jim). Born and raised in Michigan, I’ve been riding all my life. My son and my wife also regularly join me on rides. In fact, my wife and I have been riding tandem for a few decades.
