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

Bose Ultra Open Earbuds ($190, originally $299)

I've tried my fair share of earphones, but nothing beats the quality, sound, and — most importantly — the stay-put fit of the Bose Ultra Open Earbuds. These cling to the outside of your ear, so no matter how much you sweat, they won't budge. While I've liked other earbuds that hook over the ear, I have to say: nothing compares to the sound quality of these — a must for me when I run. Plus, they're sleek, compact, and even magnetically stick together, so they're less likely to get lost!
