I run ultras in the mountains where there is plenty of shade and bright light. These glasses work perfectly to cut the glare and soothe my eyes. They also work fantastic on the road as I cycle as well. You won't regret this purchase, and the polarized lenses are a step up from the carbon lenses. I have 4 pairs of these glasses and won't wear anything else!
