Watch Adam Ondra establish bold 8b ground-up on Czech sandstone

The ethics that dictate the climbing on the thousands of sandstone towers in the Czech Republic are extremely intricate. In short though they boil down to three basic rules: routes are established ground-up, nuts and friends are not used in order to avoid damaging the soft rock, and bolts - better still, the huge rings - are ideally placed by hand and extremely run-out.

In this video Adam Ondra establishes "a new crazy route" called Zpřítomnění and graded AF XIa (8b obligatory). Started a few years ago by local experts Tomáš Sobotka and Ondra Beneš at Labské údolí, the crux is comprised of "a desperate boulder problem on the very top of the tower."
