I had just fiinished climbing a sport route and had reached the bolted anchors. This particular route ended in a small “cave” so there was no visibility between the belayer and I. Once I was out of my belayer’s view and inside the “safety” of the small cave, my belayer fed me rope so I could pull the rope up easily and clip into the anchor’s draws. It’s also important to note we were trying to be efficient and climb as many routes as we could that day. With that mindset, I quickly clipped my draws and rope as soon as I saw the anchors. And then proceeded to lean back in order to weight the rope and be lowered. With plenty of slack, I fell about 5 meters. Besides a brief terrifying moment, thankfully I wasn’t injured.
