I have done a page on www.redsurfbus.com for anyone who wants to compete to get a top speed on a longboard. There are intially 3 categories, 2second peak (to eliminate spikes), 5x10second average, and 500m.
We chose to sort by 2sec as a few people this year have been trying to reach the holy grail of 30knots on a longboard which has been done a couple of time I believe.

If you want to join in you can either email me (my name on here @gmail.com) your track or the link to the site where your track is, or comment on this thread.

Good speed and winds
'The Bus'

We have a 30knot leader now....
