Kathmandu, Oct. 31 -- Fans of Nirmal Purja, who this week completed his goal of climbing all the world's 14 highest mountains in a record-shattering 6 months, have reacted strongly to those belittling his feat.

Purja climbed Mt Xixapangma (8,027m) in China on Monday, his last eight thousander in a record-shattering 190 days. The last record was by Korean climber Kim Chang-ho, who took nearly 8 years to perform the same feat. He was killed in an avalanche in Gurja Himal in Nepal last year.

Yet some mountaineering experts and climbers have downplayed the achievement, saying he used supplemental oxygen above 7,500m on all his climbs, had a team to fix ropes, and also that he did not give members of his team enough credit.
