Sometimes, we all need a motivational boost. And whenever the folks at Greatist need inspiration, we look to our community. Each week, we’ll share our favorite fitness photos — tagged with @greatist — from the Instagram community, featuring amazing fitness feats and downright heartwarming moments from across the globe.

This week, in honor of the New York Marathon, we asked users to tag their favorite photos of their own long distance runs. There are our favorites.
