(CBS News) Dutch Crown Princess Maxima swam the Amsterdam canals Sunday to raise money for charity.
Wearing a red and black swimsuit, goggles and a bright orange swim cap, the 41-year-old Argentina-born princess took about 50 minutes to make the 2-kilometer swim, according to Hello! magazine.
She was cheered on by her husband, Crown Prince Willem Alexander, and their three daughters. The oldest, Princess Amalia, 8, gave her mother a kiss when she finally emerged from the water.
The princess was among 1,000 who made the Amsterdam City Swim to raise money for ALS, a debilitating nerve and muscle disease also known as Lou Gehrig's disease.
It usually is illegal to swim in the canals, whose waters, though deemed safe, are best derscribed as murky.
