I’m André Haller, endurance athlete and coach behind Endurance Lab.

My coaching philosophy is simple: training needs a clear goal, a structured plan and enough flexibility to work in real life.

As an age-group triathlete and runner, I know the challenge of combining ambitious endurance training with a full-time job and family life. My own journey includes long-distance triathlon, a 9:30 finish at Challenge Roth and a sub-3-hour marathon.

I work with runners and triathletes who want more structure in their training – whether the goal is completing a first marathon or triathlon, improving a personal best, or preparing for a long-distance race.

Training is individually planned and adjusted using TrainingPeaks, athlete feedback and performance data. My focus is not simply on completing workouts, but on understanding the athlete, managing training load and building consistent progress over time.

Train with purpose. Progress with structure.
