Urbanchek’s Training Color System: The Palette of Swimming



There are few names as impactful in the swimming world as Jon Urbanchek, a former coach of the University of Michigan and an individual who has left an indelible mark on the world of competitive swimming. One of the most influential elements of Urbanchek's legacy is his Training Zone Color System, a revolutionary approach to individualizing training to maximize swimmer performance. This approach, which Urbanchek likened to an artistic color palette, utilizes different colors to represent various training zones, each corresponding to specific heart rates, speeds, and energy systems.


The color zones provide a straightforward yet profound way for athletes to understand their workouts, with each hue signifying a different level of intensity, duration, and physiological response. The specifics of each color in the Urbanchek palette are crucial to recognize.


White Zone

The white zone is for warm-up and cool-down, used for gentle activity that maintains a heart rate below 65% of the maximum. The white zone focuses on technique and recovery, often used in-between intense sessions.


Pink Zone

Training aerobic threshold, this zone keeps the heart rate at 70-75% of maximum. Workouts in the pink develop an endurance base, an essential element of long-distance swimming.


Red Zone

Here, swimmers aim for a heart rate of 80-85% of their maximum, marking the transition from aerobic to anaerobic training. Red zone training hones athletic aerobic capacity and helps improve race pace for longer events.


Blue Zone

This zone targets an anaerobic threshold with a heart rate of 85-90% of the maximum. Swimmers in the blue zone work to improve their lactate threshold, increasing their ability to maintain high-intensity efforts for lengthy periods.


Purple Zone

The most intense zone, the purple signifies maximal effort. Here, athletes push their heart rates above 90% of the maximum, primarily focusing on speed and power. Training in this zone is typically shorter in duration but crucial for improving sprint performance.


The beauty of Urbanchek's color system lies in its simplicity and ease of application. By assigning colors to different training zones, he made it easier for athletes to grasp the purpose of each workout and understand their physical responses to varying intensity levels.


However, not every swimmer is the same, and individual variations are necessary. Urbanchek's system is not a one-size-fits-all solution but a flexible tool to adapt to unique physiology, goals, and current performance level.


Urbanchek's system provides a foundation for coaches, allowing them to communicate effectively with their athletes with a straightforward approach to training. Coaches can paint the training canvas with various colors, encouraging a more well-rounded development of physiological capacity and ultimately leading to improved performance.


The training zone color system is more than just a tool. The system is a legacy left behind by a coach who truly understood the art and science of swimming. Urbanchek’s innovative design changed how swimmers trained but also how they understood their relationship with the water. It is an enduring contribution to swimming, a testament to Urbanchek's insightful coaching and deep understanding of the sport.


Swimming is a blend of art and science, much like Urbanchek's color palette. It takes a careful balance of technique, power, endurance, speed, and mental strength. And as swimmers continue to train using Urbanchek's color zones, they do more than swim - they create their masterpiece in the water, stroke by stroke, color by color.
