About

With the spring marathons in sight, the build toward race day has begun. Our 100 Days training program returns to Boston – an opportunity to embrace and celebrate the hard work required for the journey to 26.2 miles, featuring a series of paced long runs with the Tracksmith community designed to prepare you for race day. We aim to support your every effort as we stride closer to the starting line, offering coaching, route support, and insider discussions that will bolster your build to the marathon.
