Deadly Dozen events feature track and gym-based challenges designed to test physical endurance and strength. Deadly Run, the main event, combines 12x 400m track runs with 12 Labours (exercise stations). Gym races include Deadly Strong, focusing solely on the 12 Labours, and variations like Deadly ERG races, which integrate rowing, skiing, or biking, between Labours. From high-intensity intervals to mixed-modality endurance, these events offer participants diverse, rigorous challenges to push their limits in unique fitness competitions. The next event takes place at the University of Johannesburg Athletics Track.
