Gritstone, known to scientists as siliceous sandstone and to its British climbing devotees as 'God's own rock' is fiendishly difficult to climb. It requires a special, extremely esoteric style that relies on good friction as well as a strong stomach for long run-outs, terrible protection, and horrendous falls. There's a reason they call a proclivity for this sort of climbing 'grit madness'.
HARDXS follows four grit monkeys as they scare the living bejesus out of themselves on routes with names like 'Appointment with Death' that are both difficult and desperately bold. Take a deep breath and click through, but beware, kids, this will either want to make you to climb grit, or keep you off it forever.
