Here’s a link to an NPR story about Endo Mitsunaga,who last year became only the 13th monk since World War II to complete the Sennichi Kaihogyo – 1,000 days of walking meditation and prayer over a seven-year period around Mount Hiei. He walked 26 miles a day for periods of either 100 or 200 consecutive days, or about the same as walking around the Earth.
No bands along the course, apparently.
