Karel Sabbe to Run UTMB

From the Belgian DH News (auto-translated):

Karel Sabbe will be at the start of the UTMB Mont-Blanc at the end of August: “I want to experience this atypical atmosphere”

Has there been another athlete with the abilities to set ultra-long FKTs, succeed at Barkely and also take on an hyper-competitive event like UTMB?
