As much as we had planned, there are always unpredictable factors.

This time, for the first time, my husband joined us for this hiking trip.

It was started as my friend suddenly could not go with me for the first part, so my husband offered to come.  I considered his fitness and mountain readiness, and thought that the first part was okay for him.  So he started to train, after a period of time, he felt so good, that he wanted to come with us for the second part.

He went with me for the first mountain, the pace was really slow, but he managed to climb the the summit, and after the descending, he felt not bad, especially after onsen, he felt confident enough to go on the second mountain, but the second mountain was much harder.
