In golf, there is a feat older golfers strive for: to shoot your age.

The equivalent in open water swimming is to swim your age. To accomplish this goal, you must complete a swim equal in kilometers to your age. So if you are 20 years old, you swim your age if you do at least a 20 km swim.

If you are 30 years old, you can swim your age if you do at least a 30 km swim. At 40 years, you must do a 40 km swim. Obviously, this aquatic feat gets harder and harder as you get older.

The swim can be done in any body of water: an ocean, lake, reservoir, bay, estuary, sea, channel, canal, river, fjord or lagoon. It must be continuous (feeding stops are allowed) and completed according to the traditional rules of the sport (e.g., no touching boats, kayaks or piers, and without a wetsuit). Some say that the open water is a Fountain of Youth and those who swim their age prove it.

The annual 45.8 km Manhattan Island Marathon Swim (28.5 miles) always has people who swim their age every year. In 2011, 25 out of the 36 swimmers completed the feat:
