Matt Giunta

Data scientist, teacher, coach: I bring a wide range of professional and athletic experience into everything we do. As a triathlete, I've trained with the pros and whittled down my Ironman PR into the 10-hour range before transitioning into bike racing. With over 15 years of cutting-edge endurance coaching experience, I can provide maximum results for your coaching investment. Blueshift Multisport is the creative space where I focus my energy on a single mission: Helping athletes like YOU go faster and farther than ever before.



"I would have never seen the success of last year without Matt. As a medical student, I rely on Matt 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."

- Nick S.
Ironman 70.3 World Championship Qualifier

"As a working mom of 3 young children 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!"
