I climbed the Machambe route in 1999 which is also a day longer that the traditional Coca-Cola route which is only 4 days up.

One of my friends who does triathalons in the Bay Area also had her body shut down at about 15,000ft. She went up to the last camp at 17,000ft but did not summit with us.

Like all altitude sickness, she felt immediately better once she hiked to lower altitudes.

A friend and I are headed back to that area this Xmas to climb Mt. Kenya rockclimbing up the mountaineering route. Should be fun!
