On 22 July 2026, Garmin announced it had acquired TrainingPeaks and TrainHeroic, two of the best-known training platforms for endurance and strength coaches. For most of the last two decades, TrainingPeaks was the largest manufacturer-independent platform for structured endurance training — a neutral place to plan workouts and analyse data no matter which watch, bike computer or trainer your athletes used.
That neutrality is exactly what the acquisition has put up for discussion. If you coach athletes on a mix of Garmin, Coros, Polar, Suunto, Wahoo and Apple devices, your planning tool is now owned by a company that competes directly with several of those brands. This article looks at what actually changed, whether platform independence is worth caring about, and which endurance coaching platforms remain independent in 2026.
