3 o'clock in the morning. Deeply coiled in your sleeping bag, you struggle to open your eyes while the clock is reminding you your duty - wake up, eat a bit and light your headlamp : the climbing of the Cervin cannot wait. In Matterhorn, you have to be the first to reach to top. Throw the dice, throw them again, but stop at the right time if you don't want to waste your turn !
