Retired scientist and duathlete Bill Lankford’s terrifying brush with tick-borne encephalitis feels like something out of a sci-fi film. After an ultra-challenging swim-run across Scandinavia last August, the 62-year-old from Cambridge began suffering what he assumed were routine travel-related aches and chills.


As his symptoms intensified—persistent headaches, sleep disruption, balance challenges, and sensitivity to light—Bill consulted his GP, who initially suspected Lyme disease. But after weeks of debilitating pain that felt like an “alien trying to get out” of his head, he ended up in hospital. A cerebrospinal fluid test finally pinpointed the rare tick-borne encephalitis virus.
Despite the serious nature of his diagnosis, Bill faced it with resilience. The condition severely impacted his daily life, initially leaving him dependent on a wheelchair and walking stick while battling chronic fatigue and memory loss. However, Bill slowly rebuilt his strength, tackling short walks, bike rides, and even returning to his beloved swim-run events.

Just this past weekend, Bill celebrated completing a 22km swim-run event in Dorset, a personal victory that marks his incredible recovery. While long-distance challenges are off the table for now, he’s thrilled to be back in action, encouraging others to consider vaccination if they’re active in tick-prone areas.
Bill’s experience is a vivid reminder of how crucial it is to be mindful of tick bites and their potential consequences—even on adventurous exploits. Stay safe and alert when exploring the great outdoors! 🌳💪
