Heartbreak was born at the most notorious part of the world's most prestigious marathon. Training the athletes who challenge & persevere through Boston is how we built a global reputation for training excellence as the foundation of what we do. Today, we guide thousands of runners every year for Boston, New York, Chicago, Los Angeles, Berlin, Tokyo, and so many local and regional races.
Coaches Dan Fitzgerald (Heartbeak co-founder) and Marielle Hall (Olympian & Heartbreak GM) bring a wealth of coaching and competitive experience that will make your journey to the finish line powerful, safe, fun, & unforgettable.

Dan FitzgeraldI love what the marathon teaches people about their own capacity. It's an honor to help guide their journey.
Marielle HallBig goals aren't meant to scare you, they're meant to spark your drive. Compete against the challenge, that's the fun part!
Courtney Y.I just finished Chicago today in 3 hrs 52 minutes. I ran Boston in 2024 with a finish of 4 hrs and 27 minutes. Both times I used your marathon plans, but this time I opted for the intermediate. I can't tell you how grateful I am for what you have provided for my growth and what I presume are so many other runners as well. It was unbelievable to see Heartbreaks presence at this marathon. You have built such a special community.
Liane S.I wanted to thank you for ALL you did to support Team American Red Cross. Your weekly emails, advice, tips, encouragement were so helpful. I followed your training plan as well for this race, and it must've worked because many things went "right" for me! It was also a treat to look for and spot you at mile 20 - it was a mental check point for me. Thank you!
