I have a funny feeling those GPS goggles aren't very accurate because my dad's buddy bought some and clocked himself going at 55mph, and I know I ski a lot faster than him, and I don't think I'm getting over 55mph on scratch ghettos I never wax. My dad also wanted to see how fast he could go on our old snowlerblades and he clocked in at like 40mph riding some hill at Big Bear which doesn't even make sense.
Side note, I've been around 35mph on a skateboard (/claim), and it seemed way faster than i've ever been on skis.
Also wat is a km.
