We'll help you get started!

How much does it cost?

Only $50 per year will give you exclusive access to Zoom's Facebook group and website, where you can stay informed of ad-hoc training sessions and other team events.

Join us at Walden Pond every Wednesday morning throughout the season for open-water swim practice.

During the offseason you can find many of our members utilizing the Harvard and MIT Masters Swim programs.

We occasionally organize team swim clinics, and otherwise can be found at Walden, Mystic River Reservation or Carson Beach in Southie.

Weekend group rides in beautiful locations around Boston.

Bust your trainer boredom with indoor team spin sessions during the offseason (Saturdays on Zwift).

We also love to compete as a team at various indoor time-trials around Boston during the winter months.

Our team running events include an amazing Ragnar Cape Cod adventure and the Boston Run, a tribute to our city on the anniversary of the 2013 Boston Marathon.

During the tri season, we alternate track workouts on Tuesday evenings between South Boston and the Danehy track in Cambridge.  If track's not your thing, join us for the occasional weekend long run or a trail run!  New in 2018 are Sunday Funday Rundays around the river or meeting up at local races or running events!
