A challenge using GPS? How does it work?

The challenge sprang from a new idea. It is set up as a global contest, a challenge open to windsurfers anywhere around the world, who will be able to compete with each other from afar, measuring their times by GPS, simultaneously with the riders who are actually taking part in the race in Bonaire. There will be two diferents rankins, one for participants in Sorobon Beach and one for the rest of the world

But how is this possible?

Indeed, it is possible. Too right! If you cannot come along to Bonaire, then just sign up to the ‘worldwide’ race, the “Bonaire 2019 Dunkerbeck GPS Speed Challenge” open to competitors from around the world.
