Clean boulders provide better grip:
The abrasion of the climbing shoes and chalk from the hands scuff the handholds and footholds quickly. They can get slippery fast and lose grip. A small brush is part of the standard equipment a boulderer uses. You can purchase a brush at our front desk. Otherwise, you will find longs brushes around the climbing area to reach and clean higher boulders.
Finishing a boulder:
Most boulders end at the top-hold. If the top-hold is marked, the route of the boulder ends there, and you may climb or jump down. In some of our gyms you will find routes where a top-out is possible, meaning you simply climb over the edge to finish. In this case the end of the boulder is not marked by a label. In all other cases, never climb over the edge.
