Mt. Hiei, which straddles Kyoto and Shiga prefectures, is home to a huge temple complex called Enryakuji. The foothills of Mt. Hiei border Kyoto City’s northeast. This group of Buddhist temples is home to an eclectic group of Tendai-shu monks, dubbed the “marathon monks” for their amazing physical feats. Not all Enryakuji monks take part, mind you, as one must get special permission to engage in what is called one of the most rigorous athletic and spiritual challenges on the planet.
During the sennichi kaihogyo, or Thousand Day Challenge, the monks venerate Fudo-myo-o, the god at the center of worship in the Tendai sect. Over a seven-year training period, the monk, called a gyoja, makes a pilgrimage to over 250 sites on Mt. Hiei, one of the top three sacred spots in Japan. At the end of the challenge, he will have walked far enough to have circled the globe once. As if this were not enough to please their god, he also takes part in a fast for nine days in which he can not eat, drink or sleep. So arduous is the sennichi kaihogyo that just over 5o monks have accomplished the challenge since records started being kept back in 1585. Indeed, many monks have died en route to this ultimate quest for enlightenment.
