Additional information:
Just a heads-up for everyone: GPS-Speedsurfing is committed to maintaining the highest standards of accuracy and authenticity in our leaderboards and global results. To uphold the quality of these competitions, it's important to remember:

• Your GPS data should not exceed a frequency of 2 seconds.

• Acceleration cannot surpass 3 knots per second.

• Please be aware that older devices, such as an Apple Watch 6 or an iPhone X, might not meet these accuracy requirements due to the potential for incorrect data.

Sessions that don't align with these criteria will regrettably be excluded or removed to guarantee the fairness and precision of our competitions.

Note: this feature is available only for Pro users.
