What eyewear are you wearing for 100-milers? Starting at night, ending in full sun.
Running my first 100-miler this fall. Start is at 6pm, so I'll be running through the night and into the next day. I need eyewear that works in the dark (or at least doesn't hurt in the dark) and then handles full sun the next morning. I've been looking at active photochromic glasses. Any ultra runners using them? How do they hold up over 20+ hours?
