Our goal is to deliver a premium coaching experience for the modern endurance athlete. To forge a powerful collaboration, we design an efficient training program around your unique athletic profile, transforming your data streams into valuable insights. We follow the cutting-edge of exercise science research for innovations that merit immediate application.

At Blueshift Multisport, we strive to produce maximum results for your coaching investment.



Blueshift started in 2009 as a virtual and IRL coaching platform to help athletes navigate the original paradigm shift from high-volume (HR-based) to intensity-first (power-based) training. While much has come to light since then, Coach Matt Giunta understands that serious athletes today need hybrid solutions. He brings his professional background as a data scientist, educator, and craftsman to the coaching relationship with the intention of sharing the best tools and knowledge with committed athletes. As the data revolution continues to accelerate, the latest iteration of Blueshift coaching is designed around a focused client load. We use advanced analysis concepts and seek an engaging conversation to help YOU achieve your goals.



"I would never have seen the success of last year without Matt. As a medical student, I rely on him for every aspect of my training except for the execution -- which is all I really have time or energy for. I've been so thankful to have a coach that understands my needs, works within my means, and pushes me to the next level; a level I certainly wouldn't have been able to achieve all on my own."

"As a working mom of 3 teenagers with a demanding job, I rely on Matt's expertise to optimize the effectiveness of my workout time. Matt analyzes my results and provides me with real-time feedback and suggestions for future workouts. I can't wait to see how far I can go under Matt's guidance!"
