Bart Stevens   Delphi Human Performance Systems

Delphi HPS provides an effective, proven model for anyone seeking to achieve mastery in their physical life through a synthesis of foundational endurance principles, cutting edge technology and the hard-earned crucible of real-world competition.

The Delphi training curriculum represents the combined accumulation of knowledge and experience acquired through years of trial and error. I've rolled the dice many times at the IRONMAN distance with myself and others, so that you don't have to.


My name is Bart Stevens, and I'm in the business of changing lives.

I do this most effectively by building endurance athletes. My coaching emphasis is multisport (triathlon) with a primary focus on the long-course (i.e. "IRONMAN.")

I harbor a deep and abiding passion for the sport and lifestyle, and coaching is my way of giving back to others that which has given so much to me. In my world, swim/bike/run may not be the only fitness model around, it's just the best. Fitness trends will come and go, but no other physical training regimen produces comprehensive lifestyle improvement as reliably and consistently as a carefully-balanced combination of cardiovascular training, strength and conditioning work, nutrition management, recovery and a commitment to biohacking.
