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

Apple Watch Series 10 ($364, originally $429)

It's not necessary, but having something to track your runs is a huge benefit. The Apple Watch measures distance, heart rate, pace, and more — and honestly, the data is surprisingly insightful (turns out I run better on rainy, overcast days than sunny ones!). If you're looking to not just complete a marathon but maybe even chase a PR, this is a great tool to have on your side.
