In reply to M3MCV:
Age does not matter, at least here, but you need the endurance and an economic climbing technique to save the energy. CAF ‘Le Manuel de la Montagne’ gives an example 12 week training program for Pierra Menta competition. Two ascends in the weekend and one jogging in the week. First 800 - 1000 m/3h, next month 1400 m/4h up to 2000 m/4h (could not do that myself) and last month 1500 m/4h up to 2500 m/6h. The joggings are on Wednesdays 30 - 40 min. First month is 8000 m, then 12 000 m and last 15 000 m. I hope you are already member of some Alpine club.
My activation last Sunday on Pic de la Corne 2080 m was on 30 degree slope with a little snow. Playing with the antennas up there can be dangerous. If your rucksack starts to roll down hill, it may go really far. The major danger in the Alpes is a snow avalanche, which kills equally both inexperienced and experienced touring skiers.
For MB expedition 2 m radio is a good idea. In the news there are often expeditions that are lost some where on the MB route, but the rescue team does not find them due to bad weather conditions. If you can communicate your exact location, it could save your life. That is one reason (in addition to spotting myself) that I started to experiment with the APRS on SOTA expeditions.
