Reading this article, I got reminded of our trek to Base Camp (via Lukla) in March 2006. Interesting to note the other route to trek to Mt Everest. While having physical fitness (jogging, weights etc) can help, after the trek, we realised that mental strength (and general good health) was what was needed most. We had some real regular joggers with us, who couldn't go beyond a point. While others who rarely exercised, who reached Kala Pather. The experience is one of bitter cold (we went in mid March), loss of hunger, walking with wet shoes and socks, eating the same soups and noodles for 13 days; but all in all it stays right there in your heart and mind for ever :). You could check up our trek on this news clipping: http://www.thehindubusinessline.com/manager/2006/03/20/stories/2006032001171100.htm You can also see some of the pictures: http://flickr.com/photos/abajaj
