Suprabha Beckjord runs as a spiritual practice. She's a follower of Sri Chinmoy, who believed athletics could enhance spiritual enlightenment. So he set up various weightlifting, swimming, and distance running events. His most famous - and most grueling - is the annual Sri Chinmoy Self-Transcendence 3100 Mile Race. The race, which exceeds the distance from Boston to Los Angeles, takes place around a half- mile loop in Queens, New York. Suprabha Beckjord ran those 3100 miles for 13 years in a row. Her fastest race was 49 days and 14 hours, an average or more than 63 miles a day. Rehman Tungekar talks with her.
