You drop your containers and slide down the slope, riding the loose shale feet-first. As you near the bottom you dig in your heels, using the speed of your descent to lever you forwards into a perfect dive.

Eventually, breathless and bedraggled, you crawl out of the water and collapse side by side on the muddy shore.
