THE PEAKSWARE COLLECTIVE What do athletes and musicians have in common? A lot, actually. They both chase a “next.” They both practice like it’s not practice. They both fine tune their physical and mental beings. They both get a rush from a new mastery, no matter how incremental. And they both co-exist creatively and collaboratively as members of the Peaksware companies. Each of our platform brands has a distinct mission. But they share a common goal: to provide passionate people with the resources to take their pursuits higher. We invite you to get acquainted with our collective of performance-oriented companies that bring like-minded people together. TRAININGPEAKS TrainingPeaks develops software for coaches and athletes to track, analyze, and plan endurance training. TRAINHEROIC TrainHeroic develops software to solve the strength and conditioning needs of coaches and athletes. MAKEMUSIC MakeMusic develops software to transform how music is composed, taught, learned, and performed.

Athletes and musicians set a specific goal, get expert instruction, perform focused practice, and receive immediate feedback. And they follow these steps over and over. The path from novice to expert runs through Peaksware.
