Ultramarathon runner Kay Borleis sparked widespread viral attention after sharing a "Live Photo" from a 100-mile race in Hawaii that appears to show a dark, cloaked figure watching her from the rainforest. The incident occurred in January 2019 during the HURT 100, a grueling 100-mile endurance run through Oahu's Honolulu Mauka trails, but the footage and photos gained global media coverage years later. While Borleis was running the fourth 20-mile lap of the race, her pacing partner Cassie took several photos. Neither runner recalled passing anyone on that specific section of the trail. Later that evening, Cassie’s mother noticed a dark, cloaked entity moving past Borleis in the background of a "Live Photo". Borleis later shared on a podcast that she experienced sudden, excruciating leg pain during that exact lap, causing her to cry hysterically and ultimately drop out of the race. Describing the video, Borleis noted that the shadowy figure seemed to be observing her from the foliage. "To this day, we still don't know what it was," she wrote in a blog post.
