Last Sunday, I went a rock climbing in a climbing gym. It had several walls covered with hand and toe holds of differently colors. I tied a rope to myself and my coach held one ending of the rope, guaranteeing his safety. There were many route on the climbing wall. I chose an easy one but reached the top quickly. And then I tried a harder one, what cost me more time and effort. Though my legs kept shaken after the climb, I was very content. I am eager to go here next time and I hope I will be qualified to take part outdoor climbing soon.
