A person tends to breathe faster when running to meet the increased oxygen demands of their muscles during physical exertion. As the body's activity level rises, it requires more oxygen to produce energy and to remove carbon dioxide, a byproduct of metabolism. Faster breathing helps to supply this oxygen more efficiently and maintain optimal performance. Additionally, the increased heart rate during running supports this enhanced respiratory rate.
Your stride tends to get longer as you run faster, but, no, your legs do not.
your breath
The answer to the riddle "What is hard to catch the faster you run?" is your breath. As you run faster, your breathing becomes more labored, making it feel more difficult to catch your breath. This playful twist highlights the irony of physical exertion and the body's response to it.
Which is quicker? Heat or Cold!!! 'Heat, because can 'catch (a) cold'.
Yes, it tends to run faster and has more features
when running move arms quicker to run a bit faster, start it slow, by taking easy breaths the faster you move the quicker you will breath

Because you are using up Oxygen in your blood faster then you can replace it. Breathing gets the oxygen in, Work uses it up. If you use it up faster than you get it in you "run our of breath". (your body is telling you to "stop for a bit, and let it catch up") There are medical problems that can cause "shortness of breath" so if unsure go visit your doctor.
In a perfect world, yes. Their stride (or distance between legs when they're moving them) tends to be longer. However, it takes more energy to move the extra mass and most of the time it evens out.
no
The waves and water resist your motion.
No shoe is designed to help a person run faster. They will provide you with the comfort and fit you need to be able to run great distances but speed is ultimately up to you.
