Don't be alarmed if you see people swimming in the canals on Sunday the 3rd of September - ok, unless they are screaming for help ;). As 2000 people will swim the canals to raise money for the ALS Foundation during the 6th edition of Amsterdam City Swim.
Along the entire trail, the public (you!) can encourage the swimmers. Head to the Amstel or the finish line at Keizersgracht (crossing Reguliersgracht) for some support and fun!!
