Sharks Are Fast
Do you think you can swim faster than a shark? If you can, I would find you extremely amazing.
Olympic world record holders swimming freestyle hit about the 5 mph mark which is faster than most underwater scooters often used by recreational divers. How does that compare to a few sharks? Well, most sharks have not been reliably clocked for speed but my recommendation would be to never join a shark race. In fact, I would just observe their beauty a distance and know that there is a good chance that any shark you see will be capable of swimming faster than you can.
