The Ultimate ChallengE

September 7-16th, 2025

The Flatwater Challenge series started in 2015 when we, Flatwater, took a group of paddlers to the SUP11-City Tour. We have since traveled to Lake Tahoe, Iceland, Antelope Canyon and Vancouver Island to paddle extreme distances pushing our minds and bodies to the limits. For the 10th anniversary of the Flatwater Challenge series we're going back to where it all began - the Netherlands to complete the ultimate challenge, the SUP11-City Tour.

This challenge is not for the feint of heart, 220KM (136 miles) over 5 days throughout the northern province of the Netherlands, Friesland. Paddlers will face varying weather conditions from calm and sunny to cold, rainy, and stormy. Paddlers will take on 41-48km (25-30 mi) per day with stunning views of open fields dotted with windmills, cows, and sheep, as well as visiting eleven historical cities built since 1700. Since 2009, participants have followed the original waterways where ice skaters once conquered this historic tour on frozen waters.

Flatwater Challenge: Netherlands promises to be a ultimate endurance adventure all while raising much needed funds for Flatwater.
