You should have climbed at least one peak above 6,000 m, be comfortable on snow and ice with crampons and ropes, and be very fit before attempting Baruntse. If you have not climbed above 6,000 m, start with Mera or Island Peak.
Previous climbing
Good preparation is a successful climb of a 6,000 m peak, ideally in the Himalaya. This tells you how your body handles altitude.
Skills
You should be able to climb with crampons and an ice axe, use a harness and jumar on fixed rope, and manage a rappel.
Fitness
Train for months, with long hikes with a pack, running or cycling for endurance and strength work. A long expedition needs a strong base.
Health
Altitude illness is a real risk. Get a medical check before you go, and carry insurance that covers expedition climbing and helicopter rescue.
Training plan in short
Train for six months, with cardio, strength and long loaded hikes. Add a high-altitude trip before the climb if you can.
Gear you should know
Double boots, a high-altitude down suit or jacket, a warm sleeping bag, harness, crampons, ice axe and jumars are the core. Rent what you do not own and test it first.
Plan it
See the itinerary and permits and cost.
