My Story

Create - Work - Results

I am Brian Passenti, and I have been involved in endurance sports for over three decades. From sprint to Ironman distance triathlons, from 1 to 240+  mile foot races, I have experience with all of these and everything in between. I train athletes of varying disciplines and distances with a precision process. This process allows for the build up of strategic training phases in blocks to allow for muscle adaptation and growth in recovery. Monthly plans are built out over two weeks in advance and are loaded into the Training Peaks app- Training Peaks is the online leader in exercise analysis and the worlds most powerful fitness app. I have the understanding, knowledge, and tools to get us to your next athletic achievement. My plan is simple. We will Create a custom plan, do the Work, and achieve great Results. Lets get started today!
