The Human Limit is an information design and data visualization project that explores the evolution of human performance through the marathon. By mapping physiological milestones, historical records, and shifts in training and technology, the piece examines how endurance running has continually pushed the boundaries of what the human body can achieve. Rather than presenting data as static information, the project uses visualization as a narrative tool. It reveals patterns of progress, moments of breakthrough, and the narrowing gap between perceived and actual limits.
