Events & Pop-Ups

We are committed to training in new places and supporting local businesses and causes.  Let go of the idea that training has to happen at the same location, with the same schedule, and the same people.  Underground Training will consistently take part in local runs and fundraisers and we will even create some of our own.  Pop-up classes will be held at different locations, at different times, with new faces always dropping in.  


Follow Underground Training on Instagram and Facebook to stay up to date or download the MINDBODY App to see the schedule and book classes.

CORE then Coffee

July 23, 2017

CORE then Coffee was a great success! We  raised over $150 for the Southold Elementary School Garden.  

Thank you too North Fork Roasting Company for providing the space and the coffee! And thank you to everyone who participated and donated!

Lighthouse then Lattes

This pop up will pick back in the summer check MINDBODY!

Grab a friend and head to Horton's Lighthouse in Southold for a heart pumping workout.  You will hit the 100+ stairs a bunch of times with resistance and low intensity intervals in between.  The time will fly by and you can't beat the view!


After we knock out this workout we will head to North Fork Roasting Company for your Sunday caffeine fix!
