About 100 Days: New York City 2025

Every year as the days are getting longer and the sun starts burning hotter, marathoners pull out their calendars and circle a race date in the fall – making a commitment that they know will take time, hard work, and consistency. That’s why every summer, Tracksmith kicks off our 100 Days long run training. It’s a celebration of the commencement of a marathon build, but also a resource for runners to share the work, celebrate the journey, and prepare for race day. We focus on the key element of marathon training – the long run. And we do our best to bring you everything that you need to be successful while you’re putting in the work.

Join us in NYC as we get ready for the world's biggest marathon right here in our backyard. This year we're featuring destination runs to Beacon, NY and various points on the race course.
