Rupantar has been the race director of the Sri Chinmoy Marathon Team since 1985, having been asked by Sri Chinmoy to serve in that capacity. As well as working on the big races the US Marathon Team organise each year - the 3100 Mile Race and the Six and 10 Day Race - he also spends a considerable amount of time archiving the Marathon Team's 40 year history on this website.
Nirbhasa Magee comes originally from Ireland, but has been living for the past couple of years in Iceland. Here are a couple of interviews he had before the race start:
