Such were the hazards last summer in Jamaica, Queens, at the tenth running of the Self-Transcendence 3,100. The fifteen participants—all but two of them disciples of the Bengali Guru Sri Chinmoy, who has resided in the neighborhood for forty years—hailed from ten countries on three continents. They ran in all weather, seven days a week, from 6:00 a.m. to midnight, or until their bodies compelled them to rest. If they logged fewer than fifty miles on a given day, they risked disqualification. By their own reckoning, the runners climbed eight meters per lap, mounting and descending a spectral Everest every week and a half. They toiled in this fashion for six to eight weeks, however long it took them to complete 5,649 circuits—3,100 miles—around a single city block.
