The World's Fastest Marathon Time was set by a man in a full-length bear suit - Apparently.
In 2018, Dean Karnazes, a well-known ultramarathon runner, completed a marathon in 2:59:32 while wearing a full-length bear suit, complete with a headpiece and paws. This bizarre feat was attempted to raise money for a children's hospital and to promote the idea that "anyone can do anything" with enough determination. Karnazes is a seasoned athlete with multiple Guinness World Records to his name, and his bear suit marathon time is recognized by the International Association of Ultrarunners.
