Know what you're putting on before you head out.

The season doesn't turn all at once. It's warm at the start of the run and cold at the end, dry on the way out and raining on the way back, light when you leave and dark when you get home. Our Gear Guides settle the question a forecast can't — which baselayer for the temperature, which layer for wind and rain, which tights for a cold start and a warm finish, and which shoe for the ground you're actually on. Choose your guide, build the kit, get out the door.
