SUP stands for "Stand Up Paddling". You paddle through the water while standing on a board. You can paddle through the entire canal in about an hour. You can make it as relaxed or intense as you want. This way of moving across the water is also good for the entire body: during SUP, all muscle groups are used. This waterworkout begins in Groningen at Bij De Sluis. You can also paddle on the Hoornsemeer at Teuntje de Slak SupExperience.
