UV exposure on a 100-miler is non-trivial — 12+ hours outdoors at elevation, often above tree-line. The right glasses save your eyes (and your finish-line photo). Five picks below.

Photochromic vs polarized
Photochromic lenses auto-darken with UV — perfect for races that span dawn-to-dusk. You don't have to swap lenses; one pair handles all light.
Polarized lenses cut glare from water/wet rock — best for races in canyons, near rivers, or on snowfields. They don't auto-adjust, so you might want a backup pair.
For most ultras: photochromic is the right single-pair pick. For canyon-heavy races (Western States): polarized is worth considering. Best of both worlds: Smith Bobcat's interchangeable lens system lets you pick.
Fit matters more than lens
Sunglasses that slip down your nose at hour 6 are useless. The grip surfaces (silicone, megol, rubber pads) are non-negotiable. Try the glasses on with a vest and headband; if they slip in 30 seconds of head-shaking, they'll slip in 30 hours of running.
