This depends on your physical strength. Regular outdoor exercise may be faster, those who exercise less will be slower, and those who prefer to watch the scenery will be slower, so I can only give a rough reference value.

The altitude of Guimengding, the main peak of Mengshan Scenic Area in Shandong Province, is1156m. It takes about17km to climb from the ticket gate to the top of the mountain. Suppose you climb fast, the average speed is 4.5 kilometers per hour, and it takes about 3 to 4 hours for 17 kilometers. In addition, the higher you think about it, the more time you will spend.

Pay attention to the following points when climbing a mountain:

1, attention varies from person to person.

Although mountain climbing is a good aerobic fitness activity, it is not suitable for everyone. Patients with heart disease, epilepsy, dizziness, hypertension and emphysema need to be very careful when climbing mountains. Never climb a mountain. People suffering from arthropathy or knee and ankle injuries should not climb mountains on steep slopes or climb for a long time.

2. When climbing mountains in summer, you should take sun protection and preventive measures, and pay attention to drink plenty of water.

Before climbing a mountain in summer, apply sunscreen on bare skin, and then apply sunscreen after swimming in the water. Bring enough water and replenish water regularly, which can reduce fatigue and restore physical strength as soon as possible.

3. Pay attention to the rhythm of mountain climbing

Pay attention to the pace of climbing the mountain, don't be slow for a while. The pulse in mountain climbing is always within the target rate of aerobic fitness, and the age decreases 170 (no more than 180). Once you are a little faster, you should stop to slow down your pulse and climb again. You can stand 1 or climb again for 2 minutes. You can also rest 10 minutes to 20 minutes. Be careful not to sit down at once, but stand for a while and then sit down and rest. Be careful not to lie down and rest, put on clothes to prevent catching cold. Especially when climbing a mountain, you must keep breathing rhythm and take a big breath. Then, when climbing a mountain, climb it at a constant speed. Don't go up and down for a while. Keeping climbing at a constant speed is also a good way to maintain your physical strength.

4. Bring some essential medicines.
