The course
ONE BUOY LINE, TWO LAPS
The line of buoys is laid out in the Rijkerswoerdse lake. The full distance swims two laps of 1.9 km; Half Distance and De Eigenwijze swim one lap. The water is clear and sheltered: ideal for a fast time and a safe swim start.
The setting
THIS IS WHAT THE WATER LOOKS LIKE
The Rijkerswoerdse lake is bordered by woodland on three sides. At seven in the morning the light has just come over the trees and a single line of buoys lies in the water.
