Threshold Running Workout at MIT

Going

FREE local meetups for HYROX-like workouts at Boston tracks.

Started in July 2024 by Dimensions Physical Therapy which is a HYROX affiliate gym located in East Cambridge, owned by Sarah O'Reilly, DPT.

Sarah and her husband, Jon Holman (not a PT, but a HYROX enthusiast and founder of RoxOpt) started this club to build a local community around something we love doing. All fitness levels are welcomed and we'll help scale any workout! We like being at tracks so everyone can be together while going at their own pace. We bring HYROX equipment as well.

You don't need to be signed up for HYROX races to join, though they are an amazing experience and we recommend it!

Paying club members also get early access to HYROX tickets since we are an affiliate which is a nice perk as USA races are beginning to sell out immediately.


Waiver

Weekly track workouts are always FREE and open to everyone.
As a HYROX affiliate gym, we invest monthly to secure early access to North American race tickets—something we pass along to our paying members as they now sellout immediately.

By joining the paid tier, you’re not just getting perks—you’re helping us grow the club, add more equipment, and keep the momentum going strong!


You will gain access to 48 hour pre-public ticket purchase links for North American HYROX races and help support the club.
