It’s strange having a world record holder in my extended family. Recently I married Manuela, Markus is her cousin. I can’t for a minute imagine what it would be like going 130mph straight downhill on a 45 degree slope!!! Needless to say on our mountain bike holidays we don’t do things quite like this 
Anyway check out the video of Markus - sorry but there is a 10 second lexus car ad first. Even though it is all in German, it doesn’t take away from the madness!! Markus had to hold his breath for the duration of the whole ride otherwise the headmask was going to steam up!!
Here is it .... World record 130mph
