Can an Unfit Person Climb Mount Kilimanjaro?

Climbing Kilimanjaro is a strenuous activity that takes place over a number of days. Therefore anyone who comes to Tanzania to tackle the mountain should be in the best shape possible. Like anything else in life, some people set a goal and go full force.  Others not so much.  While some will participate in extensive training regimens to prepare for their climb, others will barely concern themselves with such matters.

But can someone who is unfit and doesn’t train succeed in reaching the top of Kilimanjaro – the highest free standing mountain in the world?

To answer this, let’s first talk about what climbing Kilimanjaro encompasses. Throughout the journey, we hike at a slow, steady pace. A look at any of our trip itineraries will show that the distance covered per day averages around five miles. The time on the trail, including lunch and rest breaks, averages around six hours per day. This is a leisurely pace of less than one mile per hour on an established trail. By trekking standards, these days would not be categorized as “strenuous.” Given these short distances and time frames, it appears certainly possible that an unfit, untrained person could climb Kilimanjaro – at least up until high camp.

The summit attempt is a different story. The ascent is made in the dark, around midnight. Climbers eat an early dinner and retire in their tents for four or five hours. At an altitude of 15,000 feet, it is not easy to sleep well. So the day begins with most people being excited and sleep deprived. The hike to the summit takes 6-8 hours with an elevation gain of 4,000 feet. It is almost always cold and windy. After reaching the summit and a joyous celebration, there is a long descent down to 10,000 feet, which takes 4-6 hours.

This is an exhausting day, and precisely what makes climbing Kilimanjaro a real challenge. Legs, lungs, joints, and mental strength are tested for even the most able bodies. The chances of an unfit person being able to complete this part of the hike fall sharply as being physically unprepared magnifies these obstacles. But it’s not out of the question for people to will themselves to finish. We have been pleasantly surprised by tough clients many times.

But let’s consider the effect of altitude. The factor that prevents most people from reaching Uhuru peak is not the physical aspect of trekking itself. It’s the inability to acclimatize to altitude. And there is no way to overcome it by being tough. If you develop anything more than mild symptoms of acute mountain sickness (AMS), you should not continue climbing.

Ultimate Kilimanjaro® guides monitor every client throughout the hike to ensure they are acclimatizing to the change in elevation. If you have worsening AMS symptoms, our guides will turn you around for your own safety. AMS is the biggest killer on Mount Kilimanjaro and we will not take chances if your health is in question.

AMS can strike anyone. But by being fit, you give your body the best chance to acclimatize. How? Everything that your body is subjected to takes some of its energy. The act of hiking, carrying a pack, consuming different food and water, sleeping in tents, the changing time zone, the uncertainty of a new activity, etc. – are all stressors that can impair the body. The goal is to minimize these other factors so the body can focus on the one big stressor that is the most likely to end your climb – the altitude. While some factors, like the weather,  are out of your control, preparing your cardiovascular system, muscles, joints and mind for climbing is totally within your control.

A nonchalant attitude about climbing Kilimanjaro can get you into trouble, or worse. Please do not go from sitting in a cubicle for decades to trekking at high altitude on a mountain that claims lives every year. It’s simply careless, irresponsible and disrespectful.

We recommend training for at least two months prior to coming to Tanzania. If you are already in hiking shape, great. If you know you are lagging in fitness, start your training earlier. Climbing Kilimanjaro has its risks. By being fit, you give yourself the best chance of climbing safely and successfully.
