Overtraining and Fatigue in Runners - Signs and Solutions #1573507 (License: Personal Use)

A cartoon-style illustration shows a male runner mid-stride, visibly exhausted: sweat droplets fly, his face is strained, tongue out, and posture collapses as he lifts one leg with exaggerated motion. His green athletic outfit and purple running shoes emphasize the sport context, while dynamic lines convey rapid movement and physical stress. The image humorously yet accurately captures acute fatigue during endurance activity.

Used on fitness blogs, sports medicine sites, or training guides to illustrate overtraining symptoms, recovery strategies, or beginner mistakes. Matches user intent seeking signs of burnout, injury prevention, or pacing advice for new runners.
