Very important for this site is that all viewers and riders have faith in the speeds that a rider has posted in a session.

The way we do that is by analysing the gps-tracks that can be downloaded from a GPS.

At this moment the overall Timekeeper (Roger van Tongeren) is available to do this work.

If you have any questions you can contact him at (roger (at) gps-speedsurfing (dot) com).
