he easiest way is to remove the shoes, tap the heel on a hard surface, and pour it out. If the soles inside your shoes are removable (and most are), take out the insert and repeat the tapping process. Then simply replace the sole insert, put the shoe back on and resume your run.
Swimming does not make one taller (or shorter). However, swimming does have several (predominantly positive) effects on the body concerning cardiovascular endurance (& strength), muscle tone/strength, the respiratory system, burning calories, one’s size/stature/build (growth), and one’s overall health/wellness. The main factor in determining one’s height is genetics. One’s genetics (DNA) is responsible for about 80% of their height. The remaining 20% is determined by external factors that can affect growth (height) such as nutrition, gender, hormones, activity, and [certain] medical conditions.
Most triathletes do at least some form of weight training. Strength training can improve strength, power, endurance, improve body composition and help correct imbalances. For triathletes looking for a competitive edge, the strength offered by regular gym sessions can be a saviour.
A tri suit, not to be confused with a triathlon wetsuit (made of thin or thick neoprene/rubber), is thin and made of fabric similar to that of a regular swimsuit- typically lycra/spandex. Therefore, a tri suit is not very thick at all. It’s about as thick as a regular women’s swimsuit/men’s swim briefs or jammers.
Furthermore, USAT, IT, & WTC (Ironman) have rules about the thickness of wetsuits. Their rules state that wetsuits can be no more than 5mm thick (at any point on the wetsuit). Thus, one’s wetsuit for their triathlon(s)/triathlon event(s) will need to be 5mm or less in thickness at any given point on the wetsuit.
Triathlon bikes are meant to be comfortable for any triathlon distance, meaning anywhere from 12 to 112 miles. While it is generally agreed that a road bike provides more comfort and control, it is equally accepted that the tri-bike aerodynamics efficiency allows for a higher speed. In conclusion, it’s a tradeoff between comfort, control, and speed, however, there may not be enough of a noticeable difference between a triathlon bike and a road bike which is set up with aerodynamic components.
