Welcome to USAFIT Boston, also known as BostonFit! We are a group of training partners and friends preparing for a marathon or half marathon. Training with our group will help you conquer mental and physical barriers to get you to your finish line. Come join us!

Registration for the 2019 season has closed.


Our season runs over 25 weeks to avoid injury and get you to your full/half marathon finish line. Our members will be training for a number of fall races such as Chicago Marathon (October 13), BAA Half Marathon (October 13), Baystate Marathon & Half (October 20), Marine Corps Marathon (October 27), Cape Cod Marathon & Half (October 26-27), New York City Marathon (November 3) and many others.

We start wherever you are. Couch potato? Seasoned marathoner? Great. No matter what your conditioning or pace, there will be others to train with. Over the course of our season, our coaches will help you achieve your personal best in a non-intimidating, fun, and safe environment.

As a member of BostonFit, you’ll receive:

  • ability-based Saturday morning group long runs;
  • season long training schedules to keep you progressing during each week;
  • encouragement and expertise from trained coaches;
  • informational seminars on running topics;
  • discounts to local running stores;
  • camaraderie and social events; and
  • a BostonFit technical T-shirt.

Miles go by faster when you’re among friends all working toward a common goal. But the even greater benefit is what happens when you conquer your own personal challenges. Our members are fitter, happier, and mentally stronger than they’ve ever been before. Our unique training changes peoples lives forever.

So come on and join us!
