(NBC) - An extreme sports athlete has reached a new high.
Mark Sluszny made a vertical run down the side of the Belgacom tower in Brussels today. The tower is more than 330 feet high.
He did it in 15-and-a-half seconds, which sets a new world record.
This feat adds to a growing list for Sluszny - he swam across the English channel, bungee jumped from a balloon and hang glided over the Andes Mountains.
