There are a lot of really tough endurance races out there, but perhaps none are harder—both mentally and physically—than the Sri Chinmoy Self-Transcendence 3100 Mile Race in Queens, New York. The whole thing takes place on a single city block, and in order to finish before the cutoff, runners have to run the equivalent of about two marathons a day for 52 days in a row. In the race’s first 22 years, only 43 people finished. This past summer producer Stephanie Joyce headed to Queens to talk with the competitors, including Israeli ultrarunner Kobi Oren, who was determined to win the race on his first attempt.
