Every year a number of competitions are organized within ESAC. During these competitions, ESACers compete with each other to call themselves the best climber or boulderaar of the ESAC!


The EBoC, ESAC Boulder Competition, takes place at the boulder wall in SSC. The EPlaKKa committee organizes this competition in collaboration with the boulderwall committee. Around 40 routes are built that everyone (including non-ESAC members) can climb. This competition takes place annually around February / March.

EPlaKKa, according to Leo
To get a good taste of this great competition, you can read a piece of EPlaKKa Champion Leo here: 

... you leave your body ...

Climbing is a sport of mind and body. The body must naturally climb, but is nevertheless guided by a strong mind. The mental peace turns into a trance. Man and rock become one. The grips present themselves wherever you touch. Your foot automatically goes to the right holf. The consciousness evaporates, you leave your body, and you see yourself. To move. Flexible, no fatigue, no pain, no fear. Only a universe of rock and bumps and blue sky. Warmth, cold, wind, they are from another world, a world that I don't know.

... The steel links tie you back ...

A feeling of floating. Gravity? Birds also have gravity, but they still fly. And I climb. I climb into an endless world of stone, millions of years old and I belong, I am one with it, I live and can live forever in this one moment. A shiny piece of steel, a chain. The universe of the climber, the sport climber, it ends with the chain. The steel links bind you back to this world, your guarantor calls, you're already there, it's cold here, hurry up! He calls your soul back into your body, but you don't want to. If only I could climb on that other planet forever. Rock and stone and eternity.

... to win the dog bowl ...

What am I doing here? Wood and plastic and a sense of what am I doing here? Compete with others for the dog bowl. The wall is not a friend but your greatest enemy, fighting from grip to grip. It is miles away from this feeling, which only occurs sporadically. The feeling you are climbing for. The empty mind, full of, of, yes, of what? From climbing, to that other world, within yourself and beyond! A climbing competition, the Eplakka. Simply, two holds further than the rest. Yeah, it's that easy!
