Every week, Heartbreak hosts runners in-person in Boston, Chicago, & LA for Boston Marathon training. Not everyone can make the sessions though. In order, to reach our Heartbreakers, non-profit partners, and other athletes training all over the world, Coaches Dan & Marielle send out a Friday intention-setting message ahead of the long runs (watch below). We'll share them here each week. Want to train for Boston with us? Learn more about Boston training powered by Nike Running here.

In-person sessions always include a kick-off with a coach, routes mapped to our two plans, water, and nutrition provided by Maurten (Maurten service begins in week 3).
