Climb after a long interval

I climbed Mt. Ege yesterday. I had not climbed mountain after I climbed Mt. Yatsuga-dake. So, it was after a long interval.
I could climb fast and powerful despite I didn't train enough. Powerful muscle and lung were sustained more than 1 month. It was nice news for me, because I'll climb Mt. Kujyu and Yufu in the week after with my son.
