The Boston Marathon Was My First Race — These Training Essentials Made All the Difference

Patagonia Women's Nano Puff Jacket ($229)

If you're training on a rainy, cold day (or in the winter, like I did), I highly recommend this puff jacket. It's lightweight, breathable, and kept me warm even on the coldest training days — I'm talking 15 degrees, with wind and snow! To top it off, I've owned my white Patagonia for years, and it still looks brand new. Yes, the white one.
