Felix Neumärker, a walking muscle according to a source, has repeated Markus Bock's Corona, 9a+, at Schneiderloch, Frankenjura.

Markus made the first ascent in 2006 and it has previously only been repeated by Adam Ondra (2009) and Alexander Megos (2013), so Felix is in good company.

Compared to Felix' first of the grade, La Rambla, Corona is not very long, only ~18 meters but very fingery and powerful.
