Training for Kilimanjaro: A 12 Week Plan That Actually Works

Kilimanjaro does not require ropes, ice axes or any technical skill. It is a walk. That is exactly why it catches out people who arrive fit, and why marathon runners turn back at Barafu while unremarkable middle aged walkers stroll onto the summit.

What the mountain asks for is not speed or peak fitness. It is the ability to walk for six to eight hours, get up the next morning and do it again, six days in a row, on progressively less oxygen, and then do a fourteen hour day at the end of it. Train for that specific thing and you will enjoy your climb. Train for a 10k and you will suffer.

The three things that actually matter

Time on your feet. Not intensity. Long, slow, boring hours of walking. Your summit day starts around midnight and finishes mid afternoon, which is a fourteen hour day at altitude on very little sleep.

Back to back days. Almost every training plan fails here. Walking eight hours on a Saturday proves nothing about how you will feel on day five. Consecutive days are the whole test.

Downhill legs. The descent from Uhuru Peak to Mweka is around 3,000 vertical metres in a day and a half, and it is what ruins knees and quads. Descending is a trainable skill and almost nobody trains it.

The 12 week build

Weeks 1 to 4: foundation

• Three walks a week of 45 to 75 minutes on any terrain, at a pace where you can hold a conversation.
• One longer weekend walk, starting at 2 hours and building to 4.
• Two sessions of leg strength: squats, step ups onto a bench, lunges, calf raises. Bodyweight is fine to begin with.
• Start walking in the boots you intend to wear on the mountain. Now, not in week 10.

Weeks 5 to 8: load and hills

• Weekend walk grows to 5 or 6 hours, on the hilliest ground you can reach.
• Start carrying your daypack with the weight you will actually carry: water, layers, camera, snacks. Around 6 to 8kg.
• Add a second weekend day. A 5 hour Saturday followed by a 3 hour Sunday teaches you more than a single 8 hour effort.
• Deliberately walk downhill. Find a hill, go up, come down, repeat. Your quads will complain, which is the point.
• Add stairs if you have no hills. A stairwell with a loaded pack is unglamorous and extremely effective.

Weeks 9 to 11: the peak

• Your biggest weekend: 6 to 8 hours Saturday, 4 to 5 hours Sunday, pack loaded, boots on.
• One weekday walk in the dark, to get used to walking by headtorch on uneven ground.
• Keep the strength work going twice a week.
• If you can get to genuine altitude, even 2,500m, do it once. It is not necessary, but it is useful information about how your body responds.

Week 12: taper

• Cut the volume in half. Two or three easy walks, nothing long, nothing heavy.
• No new boots, no new insoles, no new pack. Nothing on the mountain should be unfamiliar.
• Sleep. You will get very little of it above 4,000m.

Train with the actual kit

Every guide on this mountain has watched somebody take brand new boots out of the box at Machame Gate. Blisters on day two turn a hard trip into a miserable one, and there is no way to fix them at 4,000m.

Walk at least 60 to 80 kilometres in your boots before you fly. Wear the socks you will wear. Adjust and load the pack you will carry. Test your rain shell in actual rain, because the rainforest section on the lower slopes will find every weakness in it.

What training will not do

It will not acclimatise you. Altitude tolerance is largely genetic, it does not correlate with fitness, and no amount of hill work at sea level changes how your body handles 5,895m. This is the part people find hardest to accept.

What fitness buys you is margin. A fit walker arrives at camp with energy left, eats properly, sleeps better and copes far better with a bad night. An unfit walker arrives exhausted, cannot face food, sleeps badly and starts each day further behind. Altitude then finishes the job. That is the mechanism, and it is why training matters even though it does not directly help you acclimatise.

The other thing that buys you margin is days. A longer route with a proper acclimatisation profile will do more for your chances than an extra month of training ever will.

If you have less than 12 weeks

You can still do this. Prioritise ruthlessly: the long weekend walk with a loaded pack is worth more than everything else combined. Do that every weekend, add one weekday walk, and accept that you will work harder on the mountain than you would have with a full build. Then book the longer route.
