For those comments way earlier about GPS being inaccurate, is incorrect, it takes into account the angular difference of a slope and accurate down to a couple of meters on any axis. You don't have to do any maths with the figures you get out of the device.
I'm glad you think so! My watch recorded me here doing 265 km/h... Beat that bitches.
People, stop worrying about your bloody top speed. It means nothings. If you want to compare how fast you are go try a BX course and time yourself on it, then time your buddy for bragging rights. Some of the best days I've had on snow I never went over 65 km/h (according to my super accurate watch GPS). It's all about having fun, not trying for the land speed record!
Tried to get my max bombing down from close to the peak of whistler to the base on nice early morning groomers in -20.....ended up getting early frostbite on my nose...
Not so worried about it now haha.
