In February 2018, while competing at the Winter Equestrian Festival, Farrington suffered a devastating compound fracture of the leg. His horse, Lucifer V, bucked mid-course in a 1.30m warm-up round. The fall shattered both his tibia and fibula, requiring emergency surgery and the insertion of stabilizing rods. The pain, he said later, felt like being “shot in the leg.” What followed was a grueling recovery, relearning how to walk, rebuilding strength, and navigating the mental toll that came with it. “You have to learn to walk again. Mentally, it’s very taxing,” he told Horse & Hound.
