Maintaining a reasonable level of fitness is crucial to climb Kilimanjaro. However, summiting Kilimanjaro doesn't require athletic prowess. A healthy average would be adequate. As a guideline, we suggest assessing whether you can comfortably hike 8-10 km (5-6.2 mi). If you can do it, then you are fit enough to climb Mount Kilimanjaro.
A great exercise for hiking Kilimanjaro is running. Keep training until you can confidently jog 4-5 km (2.5 - 3.1 miles). Good training programs are available at the Nike Running Club app.
Swimming is an excellent complement. Swimming strengthens your entire body and improves your heart and lung endurance. This makes it a great addition to running. The first primarily focuses on leg endurance. Swimming takes it further by engaging the arms, core, and legs at the same time. Water buoyancy is also good for people who want to protect their joints while exercising.
Finally, it is great if you have any rural areas nearby with rough hiking trails. Aim for longer ones, ideally in the 10-15 km (6-10 mi) range. Remember, most of the Kilimanjaro hike will be uphill. So, training over longer distances in the countryside will prepare you for the climb to the Roof of Africa.
