Question 1

True or false: Jellyfish stings are the leading cause of injury in open water swimming competitions.

Accepted Answer

False. Hypothermia and exhaustion are far more common causes of injury or withdrawal. Jellyfish stings are painful but rarely force elite swimmers to quit.

Question 2

True or false: Swimming in open water burns more calories than swimming the same distance in a pool due to colder temperatures.

Accepted Answer

True. Cold water forces the body to shiver and generate heat, increasing energy expenditure. Studies show a 10–15% higher calorie burn in cold open water vs. a warm pool.

Question 3

True or false: Most open water swimmers shave their entire body to reduce friction in the water.

Accepted Answer

False. While competitive pool swimmers shave for peak races, open water swimmers rarely shave because body hair and a thin layer of oil help retain heat in cold water.

Question 4

True or false: Open water swimmers often wear two swim caps to reduce wind drag and keep their goggles secure.

Accepted Answer

True. Elite open water swimmers frequently layer two silicone caps: one to hold goggles in place, another to reduce resistance and provide thermal protection during long swims.

Question 5

True or false: The first person to swim across the Antarctic Ocean without a wetsuit did so in water just above freezing.

Accepted Answer

True. In 2019, Lewis Pugh swam 1 km in 0°C water at the South Pole in just swim trunks and a cap, highlighting extreme cold adaptation.

Question 6

True or false: The English Channel is the most swum open water crossing in the world, with over 2,000 successful solo swims.

Accepted Answer

True. Despite its cold water and strong currents, the English Channel has been swum by over 2,000 individuals since 1875, making it the most popular long-distance swim.

Question 7

True or false: Open water swimmers are forbidden from touching support boats or people during a race, but they can grab floating debris.

Accepted Answer

False. Touching any object, including debris or boats, usually results in disqualification. Swimmers may only touch their own support crew for feeding or hydration.

Question 8

True or false: Most open water swimmers prefer to breathe on every stroke to maximize oxygen intake.

Accepted Answer

False. Bilateral breathing every three strokes is more common in open water to sight buoys and waves. Every-stroke breathing is rare and disrupts rhythm.
