It is rare to find the written History of Marathon in Nepal. Nepal`s Marathon runners’ participation in Olympic has been quite regular since Nepal`s first participation in Tokyo in the year 1964.
The oldest Nepali Marathon runners are traced as Min Bahadur Bista and Gaja Raj Joshi. In the First Asian Games held in New Delhi in 1982, Gaja Raj Joshi participated for the very first time in the history of international Marathon competition.
It has been noticed that many Nepali Marathon runners have individually participated in different Marathon events of the World, but there is no statistics available.
Baikuntha Manandhar is one of the most prominent Marathon runners of Nepal, who has participated in 4 Olympic games and, held the South Asian record for quite a long time.
