Watch what went down when Halldor Helgason attempts a brand new roof gap step-up feature while filming for the new Sexual Snowboarding movie 'NoToBo'.
When you consider that these days, Halldor Helgason pretty much spends his days jumping between buildings on a snowboard, you'd be forgiven for thinking he was clinically insane.
Last year, Halldor stomped an insane backflip between two buildings and clearly set out on a mission last season to top, or at least match that feat.
In this video we get a unique first person GoPro perspective on what it felt like to speed check a roof gap that you haven't hit before, as well as what it looks like when you actually go for it.
The fact that this one is a step-up means that there is so much that could go wrong if you don't get the speed right or don't get enough pop off the kicker.
Halldor Helgason: you sir, are a madman.
